HV: vioapic: use uint8_t for pins

Browse Source 
IOAPIC pins always fit in 8-bit and we already use uint8_t for virt_pins. This
patch converts pins in vioapic to uint8_t.

This is based on Arindam's previous patch ("was: hv: Cleanup and optimise
vioapic.c"), with SOS boot failure resolved, format string updated, complex
arithmetic expression with implicit type conversion decoupled. Also make some
local variables representing interrupt vectors uint32_t.
