[PATCH] soc: imx93: fix missing clock disable in remove path

[Haotian Zhang]

The remove function never disables clocks that were enabled
in probe when the domain was initially on. The function
pm_genpd_remove() does not invoke the .power_off callback,
so clocks may remain prepared and enabled if the power domain
has not been powered off before removal.

Explicitly disable and unprepare the clocks in
imx93_pd_remove() to ensure proper resource cleanup.
