Subject: [PATCH v2] hwmon: (oxp-sensors) Add AYANEO AIR and AIR Pro

Add support for the AYANEO AIR and AYANEO AIR Pro models of handheld
devices. These devices use the same EC registers and logic as the One X
Player mini AMD. Previous AYANEO models are not supported as they use a
different EC and do not have the necessary fan speed write enable and
setting registers. Tihe driver is tested on Aya Neo AIR while AIR Pro
model EC functionality and DMI data were verified using command line
tools by another user.
The added devices are:
- AYANEO AIR (AMD 5560U)
- AYANEO AIR Pro (AMD 5560U)
- AYANEO AIR Pro (AMD 5825U)
