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.

There are multiple helpers for collecting info to be printed on the ACRN uart
console. They are unreachable code in release builds in which the uart console
is removed.
To define a precise boundary for safety-related activities, this patch wraps the
declarations and definitions to these helpers with "#ifdef HV_DEBUG" so that
these unreachable APIs will be dropped in release builds.
v1 -> v2:
* Fix coding style: no empty lines between #ifdef and the wrapped code.
* Also drop get_rte_info() in ioapic.c, which is solely used by
get_ioapic_info().

MISRA C required that return value should be used, missing for it should
add "(void)" prefix before the function call.
Some function can be declared without return value to avoid this problem.

Currently irq and vector numbers are used inconsistently.
* Sometimes vector or irq ids is used in bit operations, indicating
that they should be unsigned (which is required by MISRA C).
* At the same time we use -1 to indicate an unknown irq (in
common_register_handler()) or unavailable irq (in
alloc_irq()). Also (irq < 0) or (vector < 0) are used for error
checking. These indicate that irq or vector ids should be signed.
This patch converts irq and vector numbers to unsigned 32-bit integers, and
replace the previous -1 with IRQ_INVALID or VECTOR_INVALID. The branch
conditions are updated accordingly.
