537faf269d qtnfmac: modify supported interface combinations
Update existing code handling configuration of supported interface
combinations. Current implementation is not complete since it does
not report multiple interface combinations which are incompatible
with each other. Instead current implementation packs all the
supported combinations into single entry.

In fact currently qsr10g wireless card supports the following
two distinct interface combinations:

1. STA/repeater: 1 STA and/or 1 AP
   {
     { .max = 1, .types = NL80211_IFTYPE_AP},
     { .max = 1, .types = NL80211_IFTYPE_STA},
   }

2. AP/mBSS
   {
     { .max = 8, .types = NL80211_IFTYPE_AP},
   }

The list of supported configuration is reported by firmware during
wireless card bring-up. Communication protocol between firmware
and host has been updated accordingly in order to accommodate passing
multiple interface combination entries.

17011da0b8 qtnfmac: configure and start AP interface with a single command
Current logic artificially divides "start AP" procedure into three
stages:
- generic interface configuration (security, channel etc)
- IE's processing
- enable AP mode on interface

This separation would not allow to do a proper device configuration as
first stage needs to use information from IEs that are processed on
a second stage. Which means first and second stages have to be meged.
In that case there is no point anymore to keep third stage either, so
merge all three into a single command.

This new command carries all the same info as contained in
"struct cfg80211_ap_settings".

with channels information.
