[MIPS] page.h: remove __pa() usages.
__pa() was used by virt_to_page() and virt_addr_valid(). These latter are used when kernel is initialised so __pa() is not appropriate, we use virt_to_phys() instead. Futhermore __pa() is going to take care of CKSEG0/XKPHYS address mix for 64 bit kernels. This makes __pa() more complex than virt_to_phys() and this extra work is not needed by virt_to_page() and virt_addr_valid(). Eventually it consolidates virt_to_phys() prototype by making its argument 'const'. this avoids some warnings that was due to some virt_to_page() usages which pass const pointer.
