core: when enabling serial IRQs, unmask interrupts at the PIC 2009-09-05T00:21:10+00:00 H.

As such, enable the interrupt lines at the PIC and hope to $DEITY we don't hang due to a stuck interrupt line. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

Implement a workaround which forces INT 18h instead if an EFI signature is detected in memory. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
