The pmc driver was previously exporting tegra_pmc_restart, which was
assigned to machine_desc.init_machine, taking precedence over the
restart handlers registered through register_restart_handler().

This adds a device tree controlled option to enable PMC-based
thermal reset in overheating situations. Thermtrip is supported on
Tegra30, Tegra114 and Tegra124. The thermal reset only works when
the thermal sensors are calibrated, so a soctherm driver is also
required.
The thermtrip event is triggered by the soctherm block, and all
soctherm sensors default to showing a temperature of zero Celsius
before they are initialized. Because of this, it is safe to initialize
thermtrip and soctherm in any order.

Tegra132 uses the same GPU as Tegra124 and therefore requires the same
method to remove clamps. However Tegra132 has a separate chip ID, so in
order to avoid having to extend the list of chip IDs for the special
case, add a feature flag to the SoC data.

Tegra SoCs with 64-bit ARM support don't currently support deep CPU
low-power states in mainline Linux. When this support is added in the
future, it will probably look rather different from the existing
32-bit ARM support, since the ARM64 maintainers' strong preference is
to use PSCI to implement it.
So, for the time being, prevent the CPU suspend-related code and data
in the Tegra PMC driver from compiling on ARM64.

This commit converts the PMC support code to a platform driver. Because
the boot process needs to call into this driver very early, also set up
a minimal environment via an early initcall.
