[PATCH] backlight: sky81452: fix sky81452_bl_platform_data kernel-doc

Correct the struct name and add a short struct description to fix the
kernel-doc notation.

Prevents this kernel-doc warning:
drivers/video/backlight/sky81452-backlight.c:64: warning: expecting prototype for struct sky81452_platform_data. Prototype was for struct sky81452_bl_platform_data instead
