[PATCH RFC 2/2] platform/x86: alienware-wmi-wmax: Check for AWCC support using _UID

[Kurt Borja]

The WMAX _UID of all devices that support the AWCC is "AWCC". This
includes the following devices which were manually by reading their ACPI
tables:

  - Dell G16 7630
  - Dell G5 5505 SE
  - Alienware m16 R1
  - Alienware m17 R5 AMD
  - Alienware x15 R2
  - Alienware 17 R5
  - Alienware Aurora R12
  - Alienware Aurora Ryzen Edition

And possibly many more, if not all devices with this interface.

Add a check for "AWCC" _UID in wmax_wmi_probe() as a last resort test
for support.
