target/mips: Let get_physical_address() take MMUAccessType argument

All these functions:
- mips_cpu_get_phys_page_debug()
- cpu_mips_translate_address()
- mips_cpu_tlb_fill()
- page_table_walk_refill()
- walk_directory()
call get_physical_address() passing a MMUAccessType type. Let the
prototype use it as argument, as it is stricter than an integer.
