TRNG "sample size" (the total number of entropy samples that will be taken
during entropy generation) default / POR value is very conservatively
set to 2500.
Let's set it to 512, the same as the caam driver in U-boot
(drivers/crypto/fsl_caam.c) does.
This solves the issue of RNG performance dropping after a suspend/resume
cycle on parts where caam loses power, since the initial U-boot setttings
are lost and kernel does not restore them when resuming.
Note: when changing the sample size, the self-test parameters need to be
updated accordingly.

A QAT GEN4 device can be currently configured for crypto (sym;asym) or
compression (dc).
This patch extends the configuration to support more variations of these
services, download the correct FW images on the device and report the
correct capabilities on the device based on the configured service.
The device can now be configured with the following services:
"sym", "asym", "dc", "sym;asym", "asym;sym", "sym;dc", "dc;sym",
"asym;dc", "dc;asym".
With this change, the configuration "sym", "asym", "sym;dc", "dc;sym",
"asym;dc", "dc;asym" will be accessible only via userspace, i.e. the driver
for those configurations will not register into the crypto framework.
Support for such configurations in kernel will be enabled in a later
patch.
The pairs "sym;asym" and "asym;sym" result in identical device config.
As do "sym;dc", "dc;sym", and "asym;dc", "dc;asym".

The data structure adf_fw_config is used to select which firmware image
is loaded on a certain set of accelerator engines.
When support for 402xx was added, the adf_fw_config arrays were
duplicated in order to select different firmware images.
Since the configurations are the same regardless of the QAT GEN4
flavour, in preparation for adding support for multiple configurations,
refactor the logic that retrieves the firmware names in the 4xxx driver.
The structure adf_fw_config has been changed to contain a firmware object
id that is then mapped to a firmware name depending of the device type.

Move initialization of debugfs entries to a separate file.
This simplifies the exclusion of the debugfs logic in the QAT driver
when the kernel is built with CONFIG_DEBUG_FS=n.
In addition, it will allow to consolidate the addition of debugfs
entries to a single location in the code.
This implementation adds infrastructure to create (and remove) debugfs
entries at two different stages. The first, done when a device is probed,
allows to keep debugfs entries persistent between a transition in device
state (up to down or vice versa). The second, done after the initialization
phase, allows to have debugfs entries that are accessible only when
the device is up.
In addition, move the creation of debugfs entries for configuration
to the newly created function adf_dbgfs_init() and replace symbolic
permissions with octal permissions when creating the debugfs files.
This is to resolve the following warning reported by checkpatch:
WARNING: Symbolic permissions 'S_IRUSR' are not preferred. Consider using octal permissions '0400'.

With the update of the permanent and intermittent health errors, the
actual indicator for the health test indicates a potential error only
for the one offending time stamp gathered in the current iteration
round. The next iteration round will "overwrite" the health test result.
Thus, the entropy collection loop in jent_gen_entropy checks for
the health test failure upon each loop iteration. However, the
initialization operation checked for the APT health test once for
an APT window which implies it would not catch most errors.
Thus, the check for all health errors is now invoked unconditionally
during each loop iteration for the startup test.
With the change, the error JENT_ERCT becomes unused as all health
errors are only reported with the JENT_HEALTH return code. This
allows the removal of the error indicator.

256 bytes is quite often used in performance benchmarks and this size
appears to be also working just fine, so mark it as safe so that we do
not fallback to software implementation for this packet size. Otherwise
there is a strange bump up in crypto performance at 256 byte packet size.

Instead of duplicating the sha256 block processing code, reuse
the common code from crypto/sha256_base.h.

The function sha224_update is exactly the same as sha256_update.
Moreover it's not even used in the kernel so it can be removed.
