Firmware name for UTF mode of SDIO has changed from utf-2.bin to
utf-sdio-2.bin, so it need to change in ath10k, otherwise it will
fail for UTF mode.
After change the name in ath10k, it will success for UTF mode of
SDIO/USB.
Tested with QCA6174 SDIO with firmware
WLAN.RMH.4.4.1-00007-QCARMSWP-1.

We currently have two levels of strict validation:
1) liberal (default)
- undefined (type >= max) & NLA_UNSPEC attributes accepted
- attribute length >= expected accepted
- garbage at end of message accepted
2) strict (opt-in)
- NLA_UNSPEC attributes accepted
- attribute length >= expected accepted
Split out parsing strictness into four different options:
* TRAILING - check that there's no trailing data after parsing
attributes (in message or nested)
* MAXTYPE - reject attrs > max known type
* UNSPEC - reject attributes with NLA_UNSPEC policy entries
* STRICT_ATTRS - strictly validate attribute size
The default for future things should be *everything*.
The current *_strict() is a combination of TRAILING and MAXTYPE,
and is renamed to _deprecated_strict().
The current regular parsing has none of this, and is renamed to
*_parse_deprecated().
Additionally it allows us to selectively set one of the new flags
even on old policies. Notably, the UNSPEC flag could be useful in
this case, since it can be arranged (by filling in the policy) to
not be an incompatible userspace ABI change, but would then going
forward prevent forgetting attribute entries. Similar can apply
to the POLICY flag.
We end up with the following renames:
* nla_parse -> nla_parse_deprecated
* nla_parse_strict -> nla_parse_deprecated_strict
* nlmsg_parse -> nlmsg_parse_deprecated
* nlmsg_parse_strict -> nlmsg_parse_deprecated_strict
* nla_parse_nested -> nla_parse_nested_deprecated
* nla_validate_nested -> nla_validate_nested_deprecated
Using spatch, of course:

For this patch, don't actually add the strict, non-renamed versions
yet so that it breaks compile if I get it wrong.
Also, while at it, make nla_validate and nla_parse go down to a
common __nla_validate_parse() function to avoid code duplication.
Ultimately, this allows us to have very strict validation for every
new caller of nla_parse()/nlmsg_parse() etc as re-introduced in the
next patch, while existing things will continue to work as is.
In effect then, this adds fully strict validation for any new command.

The support to put WCN3990 firmware into Factory
test mode is not present currently. The WCN3990
firmware can operate in Factory test mode based
on the mode it receives in the wlan enable message
from the host driver.
When the host driver is started in testmode send
the operating mode as UTF mode, to the WCN3990
firmware, in the wlan enable message to start the
firmware in Factory test mode.
Tested on: WCN3990
Tested FW: WLAN.HL.2.0-01192-QCAHLSWMTPLZ-1.

The ath10k testmode uses request_firmware_direct() in order to avoid
producing firmware load warnings. Disabling the fallback mechanism was a
side effect of disabling warnings.
We now have a new API that allows us to avoid warnings while keeping the
fallback mechanism enabled. So use that instead.

Firmware files are versioned to prevent older
driver instances to load unsupported firmware
blobs. This is reflected with a fallback logic
which attempts to load several firmware files.
This however produced a lot of unnecessary
warnings sometimes confusing users and leading
them to rename firmware files making things even
more confusing.
Hence use request_firmware_direct() which does not
produce extra warnings. This shouldn't really
break anything because most modern systems don't
rely on udev/hotplug helpers to load firmware
files anymore. For example it was confirmed that
LEDE does not user helper.
This also fixes a 60 second delay per _each_
unexistent firmware/calibration file with distros
which have CONFIG_FW_LOADER_USER_HELPER_FALLBACK
enabled, RHEL being a notable example. Using
ath10k with firmware-2.bin this might end up
into a five minute delay in boot.

To make it easier to share ath10k_core_fetch_board_data_api_n() with testmode.c
refactor all firmware components to struct ath10k_fw_components. This structure
will hold firmware related files, for example firmware-N.bin and board-N.bin.
For firmware-N.bin create a new struct ath10k_fw_file which contains the actual
firmware image as well as the parsed data from the image.
Modify ath10k_core_start() to take struct ath10k_fw_components() as an argument
which makes it possible in following patches to drop some ugly hacks from
testmode.c.

Since the 10.x fw branch support was introduced it
became apparent ath10k will need to be able to
deal with different fw ABIs eventually.

command and event structures across different ABIs

ATH10K_FW_FEATURE_WMI_10X flag usage.

Add testmode interface for starting and using UTF firmware which is used to run
factory tests. This is implemented by adding new state ATH10K_STATE_UTF and user
space can enable this state with ATH10K_TM_CMD_UTF_START command. To go back to
normal mode user space can send ATH10K_TM_CMD_UTF_STOP.
