hw/arm/mps2-tz: Allow boards to have different PPCInfo data

The AN505 and AN521 have the same device layout, but the AN524 is
somewhat different.  Allow for more than one PPCInfo array, which can
be selected based on the board type.

We can't just put the arrays at file-scope and set up pointers
to them in the MPS2TZMachineClass struct, because the array
members include entries like "&mms->uart[0]" which is only valid
inside the mps2tz_common_init() function.
