Before this change, after writing "warm_hw_reset" debugfs file, host will send chip reset command to FW even though FW do not support this service getting a warning print. Though there is no FW impact before this change, this patch restricts chip reset command sent to FW only if FW advertises the support via WMI service bit. Removed the redundant check and ath10k_warn() print as well. New version FW will report chip reset service bit to host. Host allow user to trigger WLAN chip reset only when fw report this service bit. For older NON-TLV FW, since it do not report chip reset service bit, host will not send chip reset command. For older TLV FW, since it report chip reset service bit, host will send chip reset command.
