[PATCH] asm: align virt_to_phys definitions

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

We have two definitions of virt_to_phys: One for MIPS code accepting both
const and non-const pointers and one for everybody else that accepts
volatile and non-volatile pointers. Unify both to have a common
definition with the superset of the qualifiers.
