bugzilla: 182231 https://gitee.com/openeuler/kernel/issues/I4EFS1

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=b983d60292a610b21c15d3c38c6031880e58e750

--------------------------------

commit bae989c4 upstream.

The ams_delta_camera_power() function is unused as reports
Clang compilation with omap1_defconfig on linux-next:

arch/arm/mach-omap1/board-ams-delta.c:462:12: warning: unused function 'ams_delta_camera_power' [-Wunused-function]
static int ams_delta_camera_power(struct device *dev, int power)
           ^
1 warning generated.

The soc_camera support was dropped without removing
ams_delta_camera_power() function, making it unused.
