[PATCH] [media] c8sectpfe: Remove clk_disable_unprepare hacks

[peter.griffin@linaro.org (Peter Griffin)]

Now that CLK_PROC_STFE is defined as a critical clock in
DT, we can remove the commented clk_disable_unprepare from
the c8sectpfe driver. This means we now have balanced
clk*enable/disable calls in the driver, but on STiH407
family the clock in reality will never actually be disabled.

This is due to a HW bug where once the IP has been configured
and the SLIM core is running, disabling the clock causes a
unrecoverable bus lockup.
