Currently the SPARC target uses the old-style do_unassigned_access hook. We want to switch it over to do_transaction_failed, but to do this we must first remove all the direct calls in ldst_helper.c to cpu_unassigned_access(). Factor out the body of the hook function's code into a new sparc_raise_mmu_fault() and call it from the hook and from the various places that used to call cpu_unassigned_access(). In passing, this fixes a bug where the code that raised the MMU exception was directly calling GETPC() from a function that was several levels deep in the callstack from the original helper function: the new sparc_raise_mmu_fault() instead takes the return address as an argument. Other than the use of retaddr rather than GETPC() and a comment format fixup, the body of the new function has no changes from that of the old hook function.
