[Fix] The issue is introduced by commit 085749115fd37 ("wifi: mt76: mt7925: add rfkill_poll for hardware rfkill") The machine doesn't support this feature may lead to undefined behavior, and MTK will submit a firmware to fix this issue in the near feature. For short-term solution, we made a DMI quick to list the machines that doesn't support this feature. [Test] 1. Boot up HP Z2 Mini G1a Workstation 2. Run `rfkill list` to check wlan0 block state 3. Re-plug power cord and then check rfkill state again 4. The wlan0 should not be hard blocked. [Where problems could occur] Should be pretty safe to return the function call directly, since the machine doesn't support it.
