Adjust driver for changes in the FW API.
Noticeable changes in the FW are:
- temperature sensing
- infrastructure for multiple connections
- infrastructure for P2P
- signal strength indication
This commit introduces only changes that are required to support same functionality
as previous firmware, no new features.

New firmware allows for shorter SW reset procedure.
After SW reset, FW raises "fw done" IRQ, at this
moment mailbox control structures are initialized, driver caches it.
New status bit wil_status_reset_done introduced to track completion
of the reset. It is set by "fw ready" irq, and required for WMI rx flow
to access control structures.
WMI Tx flow protected by other status bit, wil_status_fwready. It can't
be set before wil_status_reset_done is set by design.

Currently the caps are parsed on every firmware reload, causing any
channel flags to be cleared.
When there is a firmware to interface mode mismatch, the triggered
firmware reload causes a reset of the regulatory settings, causing all
channels to become available:

Frequencies:
* 2412 MHz [1] (0.0 dBm)
* 2417 MHz [2] (0.0 dBm)

* 2427 MHz [4] (0.0 dBm)
* 2432 MHz [5] (0.0 dBm)
* 2437 MHz [6] (0.0 dBm)

* 2467 MHz [12] (0.0 dBm)
* 2472 MHz [13] (0.0 dBm)
* 2484 MHz [14] (0.0 dBm)

To prevent this, only parse the caps on the first firmware load during
hardware probe, and store them locally to know we have already parsed
them.

tx_timeout doesn't always lead to a cmd_timeout. There are
occurrences where cmd_timeout never gets triggered for a long
time and we encounter a kernel crash. In this patch, we track
the consecutive timeouts (tx_timeout_cnt). When tx_timeout_cnt
exceeds the threshold, trigger a card reset thereby avoiding a
kernel crash.

We allocate SKB buffers of 4K size to make sure that we process
RX AMSDU of 4K. So when skb->len is lesser than 4K; we should
modify skb->truesize. This resolves an issue where kernel has
allocated packets with 2K assumption and starts dropping packets
for large size data transfer.
This fix is already present for USB; extend it to PCIE.

The function brcmf_proto_hdrpush() increases the header space and
fills in the protocol header fields. One field is the data offset
which is currently fixed to zero meaning the data follows right
after the header. The parameter is added to determine the actual
start of data. This will be used for firmware signalling.
