USB: add arrow key support to usb_kbd
Check for scancodes for arrow keys and map them to ^F/^B, ^N/^P. Control characters are used instead of ANSI sequence because the queueing code in usb_kbd doesn't handle the data increase when one keypress generates 3 keycodes. The real fix is to convert this driver to use the input subsystem and queue, but this allows arrow keys to work until this driver is converted. Signed-off-by: Allen Martin <amartin@nvidia.com>
