[media] media: s5p-mfc: rename special clock to sclk_mfc

Commit d19f405a ("[media] s5p-mfc: Fix
selective sclk_mfc init") added support for special clock handling
(named "sclk-mfc"). However this clock is not defined yet on any
platform, so before adding it to all Exynos platform, better rename it
to "sclk_mfc" to match the scheme used for all other special clocks on
Exynos platform.
