wifi: mt76: mt7915: rework radar HWRDD idx

Browse Source 
The definition of MT_RX_SEL (for rdd_rx_sel) is mixed with the
definition of HWRDD idx.
For example, MT_RX_SEL2 is for background HWRDD idx, not an option
of rdd_rx_sel.
Therefore, add mt7915_get_rdd_idx as a helper function to get the
HWRDD idx for each variants.

Additionally, remove some parts of the code inherited from the legacy
chips.
For instance,
1. rdd_state is used for single-band-dual-HWRDD chips (for 80+80),
especially the 76xx series.
2. rdd_rx_sel is also used for single-band-dual-HWRDD chips
rx_sel = 0 => RDD0 for WF0, RDD1 for WF2
rx_sel = 1 => RDD0 for WF1, RDD1 for WF3
