target/sparc: Handle bus errors in mmu_probe()
Convert the mmu_probe() function to using address_space_ldl()
rather than ldl_phys(), so we can explicitly detect memory
transaction failures.

This makes no practical difference at the moment, because
ldl_phys() will return 0 on a transaction failure, and we
treat transaction failures and 0 PDEs identically. However
the spec says that MMU probe operations are supposed to
update the fault status registers, and if we ever implement
that we'll want to distinguish the difference. For the
moment, just add a TODO comment about the bug.
