From SDM Vol3 10.4.6:
Some processors permit software to modify the APIC ID. However, the
ability of software to modify the APIC ID is processor model specific.
Because of this, operating system software should avoid writing to the
local APIC ID register.
So to permit change APIC ID is not one *must* feature. Keep it simple,
we are also reject to modify it.
This patch does code cleaning up for LAPIC ID related emulation.

for secure and normal world has different EPTP, in secure world,
it could trap to hypervisor and call gpa2hpa function. So it need
check if it is in normal or secure world for EPTP selection.
Detailed explanation from Yadong Qi <yadong.qi@intel.com>:
Currently, trusty OS does not handle interrupt, so when an interrupt
is delivering in trusty, trusty will set it to LAPIC IRR register by
inject self_ipi() and then call world_switch to switch to Android,
So android will receive/handle the interrupt properly.Since the
vLAPIC is enabled in ACRN, so when trusty try to inject self_ipi(),
APIC-ACCESS vmexit will happen. Then ACRN will do instruction
decode/emulation, so the GPA2HPA will fail since page walk is using
nworld_eptp. It is probability an issue.

There are several similar irq handlers with confusing function names and it's
not friendly to call update_irq_handler() to update a proper handler after
request_irq().
With this commit, a single generic irq handler is being used, in which, no lock
need to be acquired because our design could guarantee there is no concurrent
irq handling and irq handler request/free.
A flags field is added to irq_desc struct to select the proper processing flow
for an irq. Irqflags is defined as follows:
IRQF_NONE (0U)
IRQF_LEVEL (1U << 1U) /* 1: level trigger; 0: edge trigger */
IRQF_PT (1U << 2U) /* 1: for passthrough dev */
Because we have only one irq handler, update_irq_handler() should be replace by
set_irq_trigger_mode(), whichs set trigger mode flag of a certian irq.
Accordingly, the code where called update_irq_handler() need to be updated.

This commit refactors vector allocation/free codes, two functions are
defined to help alloc/free vectors for an irq:
- uint32_t alloc_irq_vector(uint32_t irq)
- alloc a free vector (0x20 ~ 0xDF), and bind it to irq, for legacy irqs
and static mapped irqs, vector has been allocated and bind, so just
check the mapping correctness;
- return: valid vector on success, VECTOR_INVALID on failure.
- void free_irq_vector(uint32_t irq)
- free vector allocated via alloc_irq_vector(), for legacy irqs and static
mapped irqs, nothing need to do.
