drivers/pc80: Add PS/2 mouse presence detect
On certain Winbond SuperIO devices, when a PS/2 mouse is not
present on the auxiliary channel both channels will cease to
function if the auxiliary channel is probed while the primary
channel is active. Therefore, knowledge of mouse presence
must be gathered by coreboot during early boot, and used to
enable or disable the auxiliary PS/2 port before control is
passed to the operating system.
Add auxiliary channel PS/2 device presence detect, and update
the Winbond W83667HG-A driver to flag the auxiliary channel as
disabled if no device was detected.
