[PATCH v7 06/12] ARM: tegra: Switch CPU to PLLP on resume from LP1 on Tegra30/114/124

[Dmitry Osipenko]

The early-resume code shall not switch CPU to PLLX because PLLX
configuration could be unstable or PLLX should be simply disabled if
CPU enters into suspend running off some other PLL (the case if CPUFREQ
driver is active). The actual burst policy is restored by the clock
drivers.
