Tegra210: Remove "unsupported func ID" error msg
The platform sip is reporting a "unsupported function ID" if the
smc function id is not pmc command. When actually the smc function id
could be specific to the tegra sip handler.
This patch removes the error reported.

Tegra210: disable ERRATA_A57_829520
ERRATA_A57_829520 disables "indirect branch prediction" for
EL1 on cpu reset, leading to 15% drop in CPU performance
with coremark benchmarks.
Tegra210 already has a hardware fix for ARM BUG#829520,so
this errata is not needed.
This patch disables the errata to get increased performance
numbers.

Tegra: handler to check support for System Suspend
Tegra210 SoCs need the sc7entry-fw to enter System Suspend mode,
but there might be certain boards that do not have this firmware
blob. To stop the NS world from issuing System suspend entry
commands on such devices, we ned to disable System Suspend from
the PSCI "features".
This patch removes the System suspend handler from the Tegra PSCI
ops, so that the framework will disable support for "System Suspend"
from the PSCI "features".

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.

Tegra210: resume PMC hardware block for all platforms
The PMC hardware block resume handler was called for Tegra210
platforms, only if the sc7entry-fw was present on the device.
This would cause problems for devices that do not support this
firmware.
This patch fixes this logic and resumes the PMC block even if
the sc7entry-fw is not present on the device.
