wifi: ath12k: fix the fetching of combined rssi

Browse source

[ Upstream commit 7695fa71c1 ]

Currently, host fetches combined rssi from rssi_comb in struct
hal_rx_phyrx_rssi_legacy_info.

rssi_comb is 8th to 15th bits of the second to last variable.
rssi_comb_ppdu is the 0th to 7th of the last variable.

When bandwidth = 20MHz, rssi_comb = rssi_comb_ppdu. But when bandwidth >
20MHz, rssi_comb < rssi_comb_ppdu because rssi_comb only includes power
of primary 20 MHz while rssi_comb_ppdu includes power of active
RUs/subchannels. So should fetch combined rssi from rssi_comb_ppdu.

Also related macro definitions are too long, rename them.
