Subject: [PATCH 5.10 11/29] ARM: OMAP1: ams-delta: remove unused function ams_delta_camera_power

From: Maciej Falkowski <maciej.falkowski9@...il.com>

commit bae989c4bc53f861cc1b706aab0194703e9907a8 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.
