Grissiom 19fe6251e7 rm48x50: optimize context_switch_interrupt_to by reuse registers
When saving thread registers in context_switch_interrupt_to, we don't
change them, just move them. So there is no need to always r0-r3 from
stack to the real r0-r3. So just use the intermediate registers and
eliminate 2 MOV.
