[media] V4L: Add helper function for standard integer menu controls
This patch adds v4l2_ctrl_new_int_menu() helper function which can be used
in drivers for creating standard integer menu control with driver-specific
menu item list. It is similar to v4l2_ctrl_new_std_menu(), except it doesn't
have a mask parameter and an additional qmenu parameter allows passing
an array of signed 64-bit integers as the menu item list.
