[PATCH] ARM: tegra: Select SOC_TEGRA_PMC to fix linking error

[Krzysztof Kozlowski]

It is possible to create a ARMv7 config with ARCH_TEGRA but without any
SoC specific flavors.  Such configs fails because mach-tegra/pm.c is
compiled always and it references SOC_TEGRA_PMC driver:

	arch/arm/mach-tegra/built-in.o: In function `tegra_pm_set':
	arch/arm/mach-tegra/pm.c:188: undefined reference to `tegra_pmc_enter_suspend_mode'

I was going to apply this, when Arnd sent in a variant that fixes this
in a way that is more in line with how we handle this for other drivers.

I've credited you with a Reported-by, though.

Thanks,
