This patch adds parameter support for the 'reset' command to specify
the reboot mode (cold vs. warm).
Checking these parameters is implemented in the DM implementation.

This looks like a platform or driver specific stuff ?
Ouch, I just saw the extra printf might have to be removed in a v2...
Anyway, except for that, I don't think it's platform or driver specific.
It's just a way to make the cmd 'reset' take arguments that map to enum
sysreset_t.
There is a problem in that other platforms without UCLASS_SYSRESET don't
handle these arguments, but I thought UCLASS_SYSRESET would be the
future, and the rest would be "legacy"?
