hw/misc/mps2-scc: Support configurable number of OSCCLK values
Currently the MPS2 SCC device implements a fixed number of OSCCLK
values (3). The variant of this device in the MPS3 AN524 board has 6
OSCCLK values. Switch to using a PROP_ARRAY, which allows board code
to specify how large the OSCCLK array should be as well as its
values.
With a variable-length property array, the SCC no longer specifies
default values for the OSCCLKs, so we must set them explicitly in the
board code. This defaults are actually incorrect for the an521 and
an505; we will correct this bug in a following patch.
This is a migration compatibility break for all the mps boards.
