During init, the FW checks whether the FSEQ value matches what it
expects.  If it doesn't match, we print a warning to let integrators
clearly know that something is wrong.  This can happen if another core
(i.e. not WiFi) has updated the FSEQ version.  This notification is
only sent by the FW in production, for development firmwares, an
assertion is triggered instead.

If the OTP is empty, the NVM_GET_INFO command returns

We currently support 3 different versions of the beacon template
command and the code does some tricks in order to reuse what is
possible across these versions.  But it is a bit complicated to read
and soon there will be one more variation that the driver needs
implement, which would complicate it even further.

Refactor the way we send beacon template commands, which increases the
code size a bit, but makes it much easier to read.

There are two workarounds because RSS is currently broken on A000

Apart from DVM, all firmware uses the same base API, and there's
code outside iwlmvm that needs to interact with it. Reflect this
in the source better and reorganize the firmware API to a new
fw/api/ directory.

While at it, split the already pretty large fw-api.h file into a
number of smaller files, going from almost 3k lines in there to
a maximum number of lines less than 1k.

The cast here is wrong.  We want to cast the pointer but we accidentally
do a no-op cast of the value.  We normally want to set us_nav_upper to
WIFI_NAV_UPPER_US (30000) but because of this bug we instead set it to
184 on little endian systems and 0 on big endian ones.
