x86, 8042: Enable A20 using KBC to fix S3 resume on some MSI laptops
Some MSI laptop BIOSes are broken - INT 15h code uses port 92h to enable A20
line but resume code assumes that KBC was used.
The laptop will not resume from S3 otherwise but powers off after a while
and then powers on again stuck with a blank screen.
Fix it by enabling A20 using KBC in i8042_platform_init for x86.
