Log:
[ARM] Use bitmap to control cmse_nonsecure_call register clearing

As part of r253256, cmse_nonsecure_entry_clear_before_return has been
rewritten to use auto_sbitmap instead of an integer bitfield to control
which register needs to be cleared. This commit continues this work in
cmse_nonsecure_call_clear_caller_saved.
