[PATCH 5/8] backlight: ili922x: Add missing kerneldoc description for ili922x_reg_dump()'s arg

[Lee Jones]

Kerneldoc syntax is used, but not complete.  Descriptions required.

Prevents warnings like:

 drivers/video/backlight/ili922x.c:298: warning: Function parameter or member 'spi' not described in 'ili922x_reg_dump'
