The dtim period sent to FW was 0 because the dtim period
was never set. This caused an incorrect dtim count to be sent in
beacons.

If wowlan if off mac80211 will stop / start the driver on suspend /
resume. This causes problems on resume since request_firmware is called
from start. Fix this by caching the nv.

On some wcnss firmwares the start command can take up to 300ms to
complete. Currently there is a 200ms timeout for SMD command to
complete which causes the start to fail.
Increase the timeout to 500ms. Also improve debug information
regarding SMD command completion time.

* Response format is not in the canonical format.
wcn36xx_smd_rsp_status_check cannot be used.
* Save the FW caps in wcn36xx struct for later use.

The purpose of this housekeeping is to make some room for
VHT flags. The radiotap vendor fields weren't in use.

Commit [3469adb3: fix potential NULL pointer dereference] introduced
a check of msg_ind allocation, but omitted allocation of msg_ind->msg.
Moreover, it introduced two if statements, which looked a bit clunky.
This commit moves allocation code outside of the critical section so
there's no need to dance around mutex_unlock, and adds the missing
allocation check.

Enable the beaconing in wnc36xx by tweaking the tim offset and
force the use of AP-style beaconing. Otherwise, beaconing is not
working. The tim offset is set to 256. Otherwise, this will
overwrite mesh beacon submitted by mac80211.

These default HT parameters are required for self STA entry.
In example, set the HT capable of self STA entry for bss
configuration in mesh allows the MCS rate to be used. Otherwise,
only legacy rate will be used.

If kmalloc fails wcn36xx_smd_rsp_process will attempt to dereference
a NULL pointer. There might be a better error recovery then just
printing an error, but printing an error message is better then the
current behaviour.

This removes an open coded simple_open() function
and replaces file operations references to the function
with simple_open() instead.
