MLK-17368-2: drm: imx: dcss: split dcss_ctxld_write

In order for DTRC to work properly, we need to be able to write the DCTL
registers (to switch banks), just before activating CTXLD. However,
__dcss_ctxld_enable() function is usually called from irq context, or
whn the mutex is taken. Hence, create a function the can be called from
irq context.
