powerpc/mm: Change setbat() to take a pgprot_t rather than flags
The callers of setbat() are actually passing a pgprot_t for the flags parameter. This doesn't matter unless STRICT_MM_TYPECHECKS is enabled. So we can turn that on without breaking the build, change setbat() to take a pgprot_t and have it convert it to an unsigned long internally. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
