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.
