In commit 6d2654ffacea813916176 we created the S1Translate struct and used it to plumb through various arguments that we were previously passing one-at-a-time to get_phys_addr_v5(), get_phys_addr_v6(), and get_phys_addr_lpae(). Extend that pattern to get_phys_addr_pmsav5(), get_phys_addr_pmsav7(), get_phys_addr_pmsav8() and get_phys_addr_disabled(), so that all the get_phys_addr_* functions we call from get_phys_addr_nogpc() take the S1Translate struct rather than the mmu_idx and is_secure bool. (This refactoring is a prelude to having the called functions look at ptw->is_space rather than using an is_secure boolean.)
