The firmware advertises the LDPC support information for HT in
HT capability info in the wmi service ready event. To provide
granularity, firmware now advertises WMI_HT_CAP_RX_LDPC and
WMI_HT_CAP_TX_LDPC separately. To support LDPC, host should
also check for WMI_HT_CAP_RX_LDPC and WMI_HT_CAP_TX_LDPC in HT
capabilities.
Add a condition to existing logic in host to know whether firmware
supports LDPC or not.
