From: Sean Wang <sean.wang@xxxxxxxxxxxx>
Introduce chip_reset knob in mt7921 debugfs to export a way to users
able to trigger wifi reset, and group the similar operations
previously defined in chip_config in the same knob.
Signed-off-by: Sean Wang <sean.wang@xxxxxxxxxxxx>

v2: reuse the same knob previously defined in chip_config
