GAPK is used to calibrate RF character to make every module good
performance. With a debug switch, we can make sure if it helps in field.
Besides, we sort the register definition to make it looks better. Since
previous patchset "rtw88: add some fixes and 8822c features" also changes
the registers, I create this patchset based on the previous one, expecting
this patchset is merged later than it.

From: Guo-Feng Fan <vincent_fann@realtek.com>
This patch doesn't change logic at all, just a refactor patch.
1. Move BIT MASK and BIT definition along with the register definition
2. Remove redundant definition
3. Align macros with Tab key

From: Guo-Feng Fan <vincent_fann@realtek.com>
gap-k is a calibration mechanism to eliminate power gaps between
two nearly rate groups.
This mechanism improves performance in long range test by applying
proper power value to those rate groups which have nonlinear power gap.

Use "cat dm_cap" to show all features; where, prefix +/- means feature is
enabled/disabled:
$ cat dm_cap
DM capability 0x00000002
( 1) +TXGAPK
To control dm_cap:
use "echo +1 > dm_cap" to enable TXGAPK
use "echo -1 > dm_cap" to disable TXGAPK
Below is an example to disable TXGAPK.
$ echo -1 > dm_cap
$ cat dm_cap
DM capability 0x00000000
( 1) -TXGAPK
Below is an example to show TXGAPK status
$ echo 1 > dm_cap; cat dm_cap
( 1) +TXGAPK
