Subject: [PATCH v2 3/6] soc/tegra: pmc: Specify restart mode

From: Benjamin Bara <benjamin.bara@...data.com>

The current restart handler registration does not specify whether the
restart is a cold or a warm one. Now, as do_kernel_restart() knows about
the type, the priorization is implicitly done (cold restarts are
executed first) and the reboot_mode kernel parameter (which is currently
mostly ignored) can be respected.
