Revert "[media] omap3isp: Replace cpu_is_omap3630() with ISP revision check"

Browse source 
Reverted, as requested by Laurent:

I don't consider it as being ready yet, as Sakari pointed out we need
to investigate whether the right fix shouldn't be at the OMAP3 clocks
level instead.

This reverts commit 947c480866.
