dm: reset: have the reset-command perform a COLD reset

Browse source 
The DM version of do_reset has been issuing a warm-reset, which (on
some platforms keeps GPIOs and other parts of the platform active).
This may cause unintended behaviour, as calling do_reset usually
indicates a desire to reset the board/platform and not just the CPU.

This changes do_reset to always request a COLD reset.
Note that programmatic uses can still invoke a WARM reset through
reset_cpu() or using sysreset_walk().
