[PULL,03/10] hw/arm/aspeed_ast27x0: Use bsa.h for PPI definitions

Commit Message

From: Peter Maydell <[e-mail]>

Use the private peripheral interrupt definitions from bsa.h instead
of defining them locally.

Note that bsa.h defines these values as INTID values, which are all
16 greater than the PPI values that we were previously using.  So we
refactor the code to use INTID-based values to match that.

This is the same thing we did in commit d40ab068c07d9 for sbsa-ref.
It removes the "same constant, different values" confusion where this
board code and bsa.h both define an ARCH_GIC_MAINT_IRQ, and allows us
to use symbolic names for the timer interrupt IDs.
