I think it's not right what you're saying. Gscalers first appeared only
in exynos5 (at least according to all specifications I have) and you already
have the corresponding change for clock-exynos5.c. FIMCs in exynos 4210, 4212
and 4412 are almost not changed, so please don't rename like this, which is
confusing. If you need common clkdev entries for the exynos4 and exynos5
devices, then the "devname"s above might need to be removed and required
clock entries should be created through the CLKDEV_INIT() macro.
