ath10k: add soft/hard firmware crash option to simulate_fw_crash

Command WMI_FORCE_FW_HANG_CMDID is not supported in firmware 10.1.
In order to have firmware crash simulation functionality also
in firmware 10.1 driver can force firmware crash by performing not allowed
operation. Driver can deliberately crash firmware when setting vdev param for
vdev id out of range.  This patch introduces two keywords to simulate_fw_crash:

'soft' which will cause firmware crash that is recoverable
       by warm firmware reset but supported only in main firmware.
'hard' which will cause firmware crash recoverable by cold
       firmware reset, this option works for both firmwares.

Commands to trigger firmware soft/hard crash:

echo 'soft' > /sys/kernel/debug/ieee80211/phyX/ath10k/simulate_fw_crash
echo 'hard' > /sys/kernel/debug/ieee80211/phyX/ath10k/simulate_fw_crash

kvalo: remove '\n' before checking the command and simplify how buf is null
terminated

ath10k: update regulatory domain settings for 10.x firmware

Regulatory domain settings for firmware 10.x has more options
than main firmware, so handle regulatory domain setup separately
for both supported firmwares. Fill in additional dfs domain
parameter according to current regulatory.
This patch does not solve any known bug. Not handled parameter
for firmware 10.x was found during code review.

ath10k: fix the peer mac address in getting stats

Using the macro to convert the MAC address from WMI word
format to char array has lead to the wrong peer mac
address printed out while retrieving the peer stats from
FW. Fix this.

ath10k: fix rssi and rate reporting

RSSI and RATE fields are valid only when START_VALID
bit is set. So, in current implementation we have to
remember/caclulate them when START_VALID and report the same
when only END_VALID is set. In other case during high
RX traffic we will report invalid RSSI (-95) and RATE (6Mbps)
when only END_VALID bit set.
