Add KEYCODE_PROG_{BLUE,RED,GREEN,YELLOW} mappings to LKC equivalents
My goal is to allow colored keys on HDMI-CEC and Bluetooth remotes to be used by an Android TV app.
The USB HID spec [1] and CEC spec [2] both define distinct codes for these keys.
The kernel converts both the HID [4] and CEC [5] codes to standard LKC codes [6]:
#define KEY_RED 0x18e
#define KEY_GREEN 0x18f
#define KEY_YELLOW 0x190
#define KEY_BLUE 0x191
Android also defines KEYCODE_PROG_ constants for these keys in KeyEvent.java [3]. This commit maps these LKC codes starting at 0x18e (i.e 398) to the existing KeyEvent equivalents.
