sm8350-common: rootdir: Tuning UFS clkgate and ah8 during boot time

Disabling UFS clkgate and ah8 during boot time helps in reducing
IO delays, which helps in reducing the total boot time. This change
will disable UFS clkgate and ah8 during early-init and then enable
it back after boot completion.
