riscv: Add a reset_cpu() function

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

Note that reset_cpu() is normally provided by SYSRESET so make this
declaration conditional on that being disabled.
