We were previously using the default OSCCLK settings, which are
correct for the older MPS2 boards (mps2-an385, mps2-an386,
mps2-an500, mps2-an511), but wrong for the mps2-an505 and mps2-511
implemented in mps2-tz.c. Now we're setting the values explicitly we
can fix them to be correct.

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.

While we transition the ARMSSE code from integer properties
specifying clock frequencies to Clock objects, we want to have the
device provide both at once. We want the final name of the main
input Clock to be "MAINCLK", following the hardware name.
Unfortunately creating an input Clock with a name X creates an
under-the-hood QOM property X; for "MAINCLK" this clashes with the
existing UINT32 property of that name.
Rename the UINT32 property to MAINCLK_FRQ so it can coexist with the
MAINCLK Clock; once the transition is complete MAINCLK_FRQ will be
deleted.

We let the MPS2 boards adopt the cpu core, the FPGA and the SCC children.
While the object_initialize() function doesn't take an
'Error *errp' argument, the object_initialize_child() does.
Since this code is used when a machine is created (and is not
yet running), we deliberately choose to use the &error_abort
argument instead of ignoring errors if an object creation failed.
This choice also matches when using sysbus_init_child_obj(),
since its code is:
void sysbus_init_child_obj(Object *parent,
const char *childname, void *child,
size_t childsize, const char *childtype)
{
object_initialize_child(parent, childname, child, childsize,
