make piix/q35 compat diverge
simplify the code, use hpet_irqs to pass intcap value
v7:
use macro to define intcap in pc.h
(as to 3/4 and 4/4, I am not sure about whether to merge them or not, so keep
them separate)
v6:
move the setting of intcap to board, and keep the init value
According to hpet spec, hpet irq is high active. But according to
ICH spec, there is inversion before the input of ioapic. So the OS
will expect low active on this IRQ line. (On bare metal, if OS driver
claims high active on this line, spurious irq is generated)
We fold the emulation of this
Owning to some different hardware design, piix and q35 need
different compat. So making them diverge.
On q35, IRQ2/8 can be reserved for hpet timer 0/1. And pin 16~23
can be assigned to hpet as guest chooses. So we introduce intcap
property to do that.
Consider the compat and piix/q35, we

Previously cid of parent is parsed from image file for every IO request.
We already have L1/L2 cache and don't have assumption that parent image
can be updated behind us, so remove this to get more efficiency.
The parent CID is checked only for once after opening.

Then poke at memory to find ACPI tables.
This only checks that RSDP is there.
