backlight: ili922x: Add missing kerneldoc descriptions for CHECK_FREQ_REG() args
Kerneldoc syntax is used, but not complete. Descriptions required.
Prevents warnings like:
drivers/video/backlight/ili922x.c:116: warning: Function parameter or member 's' not described in 'CHECK_FREQ_REG'
drivers/video/backlight/ili922x.c:116: warning: Function parameter or member 'x' not described in 'CHECK_FREQ_REG'
