rtw88: 8822c: debug: allow debugfs to enable/disable TXGAPK
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
