mb/google/skyrim: Use edge (vs level) triggering for PS2K

For reasons currently unknown, using a level triggered interrupt for the
PS2 keyboard causes an IRQ storm under Windows when any key is pressed,
leading to audio distortion/dropouts. Work around this by using an edge
triggered interrupt instead.

BUG=none
TEST=build/boot Win11, Linux on google/skyrim (frostflow), verify kb
functionality, verify no IRQ storm or audio stutter/distortion under
Windows.
