The OPP core now provides a unified API for setting all configuration
types, i.e. dev_pm_opp_set_config().
Lets start using it.

Explain why special handling was required here, it isn't obvious at all.

Previously we assumed that devm_tegra_core_dev_init_opp_table() will
be used only by drivers that will always have device with OPP table,
but this is not true anymore. For example now Tegra30 will have OPP table
for PWM, but Tegra20 not and both use the same driver. Hence let's not
print the error message about missing OPP table in the common helper,
we can print it elsewhere.

GENPD core now can set up domain's performance state properly while device
is RPM-suspended. Runtime PM of a device must be enabled during setup
because GENPD checks whether device is suspended and check doesn't work
while RPM is disabled. Instead of replicating the boilerplate RPM-enable
code around OPP helper for each driver, let's make OPP helper to take care
of enabling it.

of_find_node_by_path() acquires a reference to the node returned by it
and that reference needs to be dropped by its caller. soc_is_tegra()
doesn't do that, so fix it.

Subsequent patches will move some of the initialization code from SoC
setup code to regular initcalls. To prevent breakage on other SoCs in
multi-platform builds, these initcalls need to check that they indeed
run on Tegra.
