ARM: omap1: ams-delta: remove camera leftovers

The obsolete camera support was removed, but a few lines remain in this
file and cause a warning:

arch/arm/mach-omap1/board-ams-delta.c:462:12: warning: 'ams_delta_camera_power' defined but not used [-Wunused-function]
  462 | static int ams_delta_camera_power(struct device *dev, int power)

Remove this and all related lines as well.

Fixes: ce548396 ("media: mach-omap1: board-ams-delta.c: remove soc_camera dependencies")
