drivers/pc80/pc: Split up PS/2 keyboard/mouse ACPI definitions

Separate these so a mainboard can describe a PS/2 keyboard without a
PS/2 mouse or vice-versa.

Librem 11 has a PS/2 keyboard for the volume keys, but does not have a
PS/2 mouse, and the presence of a mouse device can cause the cursor to
appear on the desktop incorrectly.

ps2_controller.asl remains since many boards include it, it now just
includes the two new files.
