media: i2c: ov6650: Drop unused driver

The ov6650 driver was introduced in v2.6.37 to support the OMAP1-based
Amstrad Delta video phone. The platform still has a board file in the
kernel, but support for the camera was dropped in commit ce548396a4
("media: mach-omap1: board-ams-delta.c: remove soc_camera dependencies")
in v5.9. The driver has been unused since as it has received neither
ACPI nor DT support.

The ov6650 driver is one of the last sensor drivers calling
clk_set_rate(). This is deprecated, and calls to the function are being
removed to avoid cargo-cult. As the driver is unlikely to ever be used
again, drop it instead of trying to avoid call clk_set_rate().
