    target/sparc: Replace legacy st_phys() -> address_space_st()

    Prefer the address_space_ld/st API over the legacy ld_phys()
    because it allow checking for bus access fault.

    get_physical_address() already accessed the PTE stored at
    %pde_ptr and is going to update it. Assume the address space
    is also writeable there. The SPARC v8 manual only mentions
    faults (with error condition bits updated) in the READ path
    but not on the WRITE (update) one.
