x86/hvm: Centralize and simplify the RTC IRQ logic.

This keeps the behaviour of strobing the IRQ line every time any RTC
interrupt source is raised.  I rather suspect (based on the behaviour
of the MC146818A RTC) that we ought to be suppressing all subsequent
interrupts whenever RTC_IRQF is set, but this way avoids making
guest-visible changes.
