[PATCH 04/14] target/arm/ptw: Pass ptw into get_phys_addr_pmsa*() and get_phys_addr_disabled()

[Peter Maydell <peter.maydell@linaro.org>]

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.)
