Subject: [PATCH] soc/tegra: Fix an error handling path in 'tegra_powergate_power_up()'
If an error occurs after a successful 'tegra_powergate_enable_clocks()'
call, it must be undone by a 'tegra_powergate_disable_clocks()' call, as
already done in the below and above error handling paths of this function.
Update the 'goto' to branch at the correct place of the error handling
path.
Fixes: a38045121bf4 ("soc/tegra: pmc: Add generic PM domain support")
