[PATCH 2/6] media: pxa_camera: Drop the v4l2-clk clock register

[Ezequiel Garcia <ezequiel@collabora.com>]

Now that mach-based PXA platforms are registering proper
fixed-rate clocks through the CCF, the v4l2-clk clock
is no longer required.

Drop this clock, so the driver no longer depends on the
legacy v4l2-clk API.
