soc/tegra: pmc: Prevent racing with cpuilde driver

Both PMC and cpuidle drivers are probed at the same init level and
cpuidle depends on the PMC suspend mode. Add new default suspend mode
that indicates whether PMC driver has been probed and reset the mode in
a case of deferred probe of the PMC driver.

soc/tegra: pmc: restrict compilation of suspend-related support to ARM

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.
