omap2/3: ZOOM: Correcting key mapping for few keys

Keys: 'right arrow', 'up arrow' and 'select' were mapped
wrongly. This patch corrects them.
This patch also adds one missing key present in the board,
currently I added it as 'unknown' key, as I am not able to
find proper description for this key.
One key entry (r: 7, c: 5) is present in the keymap, which
is really not present in the board, removing it.
