GICv3: Allow probe for fewer GICR interfaces than exposed by the frame
Previously the GICv3 redistributor probe function
(gicv3_rdistif_base_addrs_probe()) asserted that the number of
per-CPU redistributor interfaces expected to be probed by the
platform is equal to the number exported by the redistributor
frame. This is a problem in case the number of CPUs in the
platform is less than the number of redistributor interfaces
in the frame. Hence this patch removes the assertion check
and allows probe for fewer redistributor interfaces as required
by the platform.

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.
