arch: define CONFIG_PAGE_SIZE_*KB on all architectures
Most architectures only support a single hardcoded page size. In order to ensure that each one of these sets the corresponding Kconfig symbols, change over the PAGE_SHIFT definition to the common one and allow only the hardware page size to be selected.
