[PATCH] ath11k: change to treat alpha code na as world wide regdomain

[Wen Gong]

Some firmware versions for WCN6855 report the default regdomain with
alpha code "na" by default when load as a world wide regdomain, ath11k
should treat it as a world wide alpha code.

Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-01720.1-QCAHSPSWPL_V1_V2_SILICONZ_LITE-1
