mb/google/zork: Correct PIRQ_MISC0 configuration
The current configuration is masking off IRQ 1 and IRQ 12 to the PIC.
This for some reason causes problems when using level triggered
interrupts. This change updates the PIRQ_MISC0 value to match what
skyrim is doing. This will enable level interrupts to work correctly.
BUG=b:218874489, b:160595155
TEST=Boot zork and verify keyboard still works. Boot with patch train
and verify keyboard works as expected.
