The BL handover interface stores the bootloader arguments in
registers r9-r12, so when the reset_handler stores the lr pointer
in r10 it clobers one of the arguments.
Adapt to use r8 and adapt the comment about registers allowed
to clober.
I've checked aarch32 reset_handlers and none seem to use higher
registers as far as I can tell.
Fixes:
