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.
