iwlwifi: mvm: use firmware LED command where applicable
On devices starting from 8000 series, the host can no longer toggle the LED through the CSR_LED_REG register, but must do it via the firmware instead. Add support for this. Note that this means that the LED cannot be turned on while the firmware is off, so using an arbitrary LED trigger may not work as expected.
