Subject: [PATCH] staging: bcm2835-camera: Use enums for max value in
 controls

Controls of type MMAL_CONTROL_TYPE_STD_MENU call v4l2_ctrl_new_std_menu
with a max value and a mask. The max value is one of the defined
values for the control, however in the config array there are several
entries where raw numbers have been used instead. Replace these
with the appropriate enum.
