core: remap: fix regmap_init_mem_plat() reg size handeling

The fdt_addr_t and phys_addr_t size have been decoupled.
A 32bit CPU can expect 64-bit data from the device tree parser,
so convert regmap_init_mem_plat() input to handel both. The
syscon class driver also makes use of the regmap_init_mem_plat()
function, but has no way of knowing the format of the
device-specific platform data. In case of odd reg structures other
then that the syscon class driver assumes the regmap must be
filled in the individual syscon driver before pre-probe.
Also fix the ARRAY_SIZE divider in the syscon class driver.
