RDD_DET_MODE is a firmware command intended for testing and does not
pause TX after radar detection, so remove it from the normal flow;
instead, use the MAC_ENABLE_CTRL firmware command to resume TX after
the radar-triggered channel switch completes.

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.
Additionally, HWRDD idx does not exactly map to band idx for
Connac 3 chips. So, add mt7996_get_rdd_idx as a helper function.
Finally, 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
Chip Variants | 5G rdd idx | Background rdd idx
---------------------------|----------------|-------------------
MT7996 (except 205/255) | 1 | 2
MT7992 | 1 | 2
MT7990 | 1 | 2

Some of the variants do not support background radar, so add a
helper to report background radar capability.

even if the action is UNI_CHANNEL_RX_PATH, it'll still generate some
