[Bug 2127044] Re: MT7925 wifi is hard blocked on HP's machine

The firmware leads to regression, so we need to carry the sauce patch to 6.17 kernel.
6.17-OEM - https://kernel.ubuntu.com/forgejo/kernel/noble-linux-oem/pulls/350
6.17-Q - https://lists.ubuntu.com/archives/kernel-team/2026-January/165070.html

Bug description:
[Impact]
The wifi is hard blocked and can't be used randomly.

[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.
