mt76: overwrite default reg_ops if necessary

Browse Source 
Introduce mt76_register_debugfs_fops routine in order to
define per-driver regs file operations and make sure the
device is up before reading or writing its registers

Fixes: 1d8efc741df8 'mt76: mt7921: introduce Runtime PM support'
Fixes: de5ff3c9d1a2 'mt76: mt7615: introduce pm_power_save delayed work'
