hpet: enable to entitle more irq pins for hpet
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 finally have the following
value for intcap: For piix, hpet's intcap is hard coded as IRQ2.
For pc-q35-1.7 and earlier, we use IRQ2 for compat reason. Otherwise
IRQ2, IRQ8, and IRQ16~23 are allowed.
