[PATCH v1.1 07/14] media: omap3isp: remove unused clkdev

[Laurent Pinchart <laurent.pinchart@ideasonboard.com>]

From: Russell King <rmk+kernel@arm.linux.org.uk>

No merged platform supplies xclks via platform data.  As we want to
slightly change the clkdev interface, rather than fixing this unused
code, remove it instead.

In case this would be helpful, I've rebased the original patch on top of the
linuxtv master branch scheduled for merge in v4.1.
