media: i2c: Drop unused sr030pc30 camera sensor driver

The sr030pc30 camera sensor driver doesn't support DT and relies on
platform data. No board file has ever provided platform data for that
device. The driver has thus never been used in the mainline kernel since
its introduction in v2.6.37. Drop it.
