AR9003 series allows to calibrate noise floor for different frequency
bins. Once it's done it's possible to get more accurate rssi/signal
values over whole frequency band at a given temperature.
The RSSI/signal accuracy reported by calibrated RF cards improves
from 6 to up to 2dB.

This could be interesting for application which require good signal
accuracy like roaming or mesh protocols.

Currently when we want to bring the interface up, we first
reset the device which causes the boot loader to run. Then
we halt the device CPU, load FW image and resume the device
CPU.
There are some boot loader versions which perform redundant
memory accesses even when idle. Halting the device CPU
while boot loader access memory can cause the device memory
controller to get stuck, the FW will fail to load and the
network interface will not come up.
For such boot loaders implement a workaround where we freeze
the boot loader before halting the device CPU, so it will not
perform any memory accesses.

When using the firmware api it can fail simply because firmware does
not like the request or it fails due to issues in the host interface.
Currently, there is only a single error code which is confusing. So
adding a parameter to pass the firmware error separately and in case
of a firmware error always return -EBADE to user-space.

Although not really well documented these should only return an
error code in case of an error, or 0 upon success. In the bcdc
protocol it can return value above 0 and we carry a fix in the
caller of the protocol layer api. This patch makes it adhere to
the intent of the api as described above.

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.
