soc/tegra: pmc: Export tegra_powergate_power_on()
tegra_powergate_sequence_power_up() powers up partition and also enables
clock & reset. However, if a controller like PCIe have multiple clocks
& resets and they need to be enabled in a sequence, driver must use
standalone function tegra_powergate_power_on() to power up partition.
Export tegra_powergate_power_on() to allow Tegra controller drivers to
unpower gate partition independent to clock & reset.
