ppc: Add a reset_cpu() function

The current do_reset() is called from a command context. Add a function
which can be used from anywhere, as is done on ARM.

This is only needed if CONFIG_SYSRESET is disabled.

Since there are lots of reset functions, this one actually just calls
do_reset(). Future refactoring could correct this.
