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.
