[RAMEN9610-10029][COMMON] media: mfc: fix the clock on sequence

When the clock on with drm instance, the sequence is changed as following:
cache flush (cmd 12) -> clock off -> set DRM base address
-> IP protection enable -> clock on
The base addr and protection control should be applied before clock enable
because the MFC core can run immediately when the clock enable.
