Tegra210: secure PMC hardware block

This patch sets the "secure" bit to mark the PMC hardware block
as accessible only from the secure world. This setting must be
programmed during cold boot and System Resume.

The sc7entry-fw, running on the COP, needs access to the PMC block
to enter System Suspend state, so "unlock" the PMC block before
passing control to the COP.
