PWM controllable fan (G12A/B/SM1)
Commit provides two new overlays. One for the BananaPi CM4IO
Baseboard "GPIOH_5" and another for general use "GPIOX_5".
CM4IO HEADER PINS: 5V "4"; GND "6"; PWM "7"
On other units the location of the PWM HEADER PIN may vary,
so users will need to either review the wiki or schematic
of said unit.
Fan used in testing:

Modded the overlays to be specific to the unit they were made
to be used on.
