To add MLD, reuse the bss_conf structure later for per-link
information, so move some things into it that are per link.
Most transformations were done with the following spatch:

Allow the caller to pass the clock type to iwl_mvm_get_sync_time() so
callers with different needs can decide whether to use boottime or
realtime.

debugfs can now report an error code if something went wrong instead of
just NULL. So if the return value is to be used as a "real" dentry, it
needs to be checked if it is an error before dereferencing it.
This is now happening because of ff9fb72bc077 ("debugfs: return error
values, not NULL"). If multiple iwlwifi devices are in the system, this
can cause problems when the driver attempts to create the main debugfs
directory again. Later on in the code we fail horribly by trying to
dereference a pointer that is an error value.

When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.

Currently we have a boolean variable for each cause.
This costs space, and requires to check each separately
when determining low latency.
Since we have another cause incoming, convert it to an enum.
While at it, move the retrieval of the prev value and the
assignment of the new value to be inside iwl_mvm_update_low_latency
and save the need for each caller to do it separately.

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.

It's safer to use scnprintf() here because the buffer might
be too short for the full format strings. In most cases
this isn't true because of external limits on the values.
In one case, this fixes a stack data leak.

In a000 devices we will support up to 32 stations.
The max station define is used also for invalid station marking
which makes finding usages of actual maximum station pretty hard
to sort through - change it to be a different define in order
to make future changes easier.
Use also ARRAY_SIZE intead of define when possible.
Do not move yet to 32 stations until firmware do it though.

Getting the mvm station out of station id requires dereferencing
the station id to get ieee80211_sta, then checking for pointer
validity and only then extract mvm station out.
Given that there are helpers to do it - use them instead of
duplicating the code whenever we need only mvm station.

This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.
