rtems: Parameter types in rtems_partition_create()

Use uintptr_t to specify the length of the partition buffer area instead
of uint32_t.  This is in line with rtems_region_create().  On 64-bit
targets, the length may exceed 4GiB.  Use size_t for the buffer size,
since on some targets the single object size is less than the overall
address range, e.g. m32c sizeof(uintptr_t) > sizeof(size_t).

Update #3486.
