tegra132: psci: add cpu_on/off support
The CPU on/off functions are the method for the Kernel to support CPU
hot-plug function in PSCI. To support this, we still need flow controller
support to capture the WFI from the CPU and inform PMC to power gate the
CPU core. On the other path, we turn on the CPU by toggling the PMC and
use flow controller to let go when the power is steady.
BUG=chrome-os-partner:32136
BRANCH=None
TEST=built the kernel with PSCI enabled,
check both of the CPUs are coming up,
test the CPU hot-plug is working on Ryu
