drvs/intel/gma/acpi: Add methods to use MBOX3
* Add Mailbox 3 driver
* Request brightness change through Mailbox 3
* Return Ones on error or if unsupported
* Mark existing code as legacy
(still required if no GMA driver is running)
* Call legacy code if Mailbox 3 is unsupported, on error or
if gma driver isn't running
Tested on Lenovo T430:
* Brightness control still works
* Brightness is the same on S3 resume
