qcacmn: Get 2g vht20 capability from F/W

Add WMI_HOST_REGDMN_MODE_11AC_VHT20_2G in WMI_HOST_REGDMN_MODE
bitmap.

WMI_SERVICE_READY_EVENT indicates ht/vht capability by
hal_reg_capabilities-> wireless_modes, REGDMN_MODE_11AC_VHT20_2G
indicates 2g vht20, check and save it as
WMI_HOST_REGDMN_MODE_11AC_VHT20_2G.
