These four architectures define the same Kconfig symbols for configuring
the page size. Move the logic into a common place where it can be shared
with all other architectures.

Using 32KiB page size will result in slightly higher performance
kernel at the price of higher memory consumption compared to
16KiB pages. This option is available only on cnMIPS cores.

Using 64KiB page size will result in slightly higher performance
kernel at the price of much higher memory consumption compared to
4KiB or 16KiB pages.
