platform/x86: apple-gmux: Move port defines to apple-gmux.h

Browse Source 
This is a preparation patch for adding a new static inline
apple_gmux_detect() helper which actually checks a supported
gmux is present, rather then only checking an ACPI device with
the HID is there as apple_gmux_present() does.

Fixes: 21245df307 ("ACPI: video: Add Apple GMUX brightness control detection")
