De-assert PIC IRQs properly at APIC level

[ Taking latest isapc changes into account. ]

Ensure that PIC-delivered IRQs are properly de-asserted in case the APIC
is in EXTINT or FIXED mode (with level-triggering selected) on LINT0.
Fixes EFI-BIOS boot issues.

This patch also cleans up a bit the interface between PIC and APIC,
making apic_local_deliver private again.
