Subject: [PATCH v2 0/2] hid-asus: asus-wmi: refactor Ally suspend/resume

This short series refactors the Ally suspend/resume functionality in the
asus-wmi driver along with adding support for ROG Ally MCU version checking.

The version checking is then used to toggle the use of older CSEE call hacks
that were initially used to combat Ally suspend/wake issues arising from the MCU
not clearing a particular flag on resume. ASUS have since corrected this
especially for Linux in newer firmware versions.

- hid-asus requests the MCU version and displays a warning if the version is
  older than the one that fixes the issue.
- hid-asus awill also toggle the CSEE hack off, and mcu_powersave to on if the
version is high enough.

- Changelog:
  + V2:
    - Adjust warning message to explicitly mention suspend issues
    - Use switch/case block to set min_version
      - Set min_version to 0 by default and toggle hacks off
