Change the page size computation logic to default to 16KB pages, and only restrict to 4KB if the kernel is configured with R5000 or RM7000 family support.
Change the page size computation logic to default to 16KB pages, and only
restrict to 4KB if the kernel is configured with R5000 or RM7000 family support.

Allow the kernel configuration to override this if it knows better (e.g. an
upcoming kernel configuration with support for R5000, but where physical
memory on R5000 systems fits within the first 512MB).
