AMD sensor fusion hub on newer platforms require additional support to

Backport latest addition to amd_sfh.

This is backport request from AMD for an upcoming platform. We don't
have access on the hardware to test it.

[Where problems could occur]
The driver uses MMIO read to get hardware version, so as soon as the
reading is reliable the impact is limited.

  HID: amd_sfh: Extend driver capabilities for multi-generation support
  HID: amd_sfh: Extend ALS support for newer AMD platform
  HID: amd_sfh: Add initial support for HPD sensor
