i386/pc386: Fix interrupt support.
Fix the interrupt and stop the spurious interrupt from happening.
The fix moves the EOI to C code and cleans that functionality out
of the asm part of the ISR handler.
The code checks the ISR and IRR registers on the enable.
Only ack the master for a slave IRQ if the slave has no other pending
requests.
