Tegra210: suspend/resume bpmp interface across System Suspend

The BPMP firmware takes some time to initialise its state on exiting
System Suspend state. The CPU needs to synchronize with the BPMP during
this process to avoid any race conditions. This patch suspends and resumes
the BPMP interface across a System Suspend cycle, to fix this race.

Tegra: support for System Suspend using sc7entry-fw binary

This patch adds support to enter System Suspend on Tegra210 platforms
without the traditional BPMP firmware. The BPMP firmware will no longer
be supported on Tegra210 platforms and its functionality will be
divided across the CPU and sc7entry-fw.

The sc7entry-fw takes care of performing the hardware sequence required
to enter System Suspend (SC7 power state) from the COP. The CPU is required
to load this firmware to the internal RAM of the COP and start the sequence.
The CPU also make sure that the COP is off after cold boot and is only
powered on when we want to start the actual System Suspend sequence.

The previous bootloader loads the firmware to TZDRAM and passes its base and
size as part of the boot parameters. The EL3 layer is supposed to sanitize
the parameters before touching the firmware blob.

To assist the warmboot code with the PMIC discovery, EL3 is also supposed to
program PMC's scratch register #210, with appropriate values. Without these
settings the warmboot code wont be able to get the device out of System
Suspend.

Tegra210: support for cluster idle from the CPU

This patch adds support to enter/exit to/from cluster idle power
state on Tegra210 platforms that do not load BPMP firmware.

The CPU initates the cluster idle sequence on the last standing
CPU, by following these steps:

Entry
-----
* stop other CPUs from waking up
* program the PWM pinmux to tristate for OVR PMIC
* program the flow controller to enter CC6 state
* skip L1 $ flush during cluster power down, as L2 $ is inclusive
of L1 $ on Cortex-A57 CPUs

Exit
----
* program the PWM pinmux to un-tristate for OVR PMIC
* allow other CPUs to wake up

This patch also makes sure that cluster idle state entry is not
enabled until CL-DVFS is ready.
