ARM: dts: imx6sl: add keypad support for i.mx6sl-evk board.
i.MX6SL EVK board has a 3*3 keypad matrix to support 8 keypads,
enable them, the keymap is as below:
SW6: MATRIX_KEY(0x0, 0x0, KEY_UP) /* ROW0, COL0 */
SW7: MATRIX_KEY(0x0, 0x1, KEY_DOWN) /* ROW0, COL1 */
SW8: MATRIX_KEY(0x0, 0x2, KEY_ENTER) /* ROW0, COL2 */
SW9: MATRIX_KEY(0x1, 0x0, KEY_HOME) /* ROW1, COL0 */
SW10: MATRIX_KEY(0x1, 0x1, KEY_RIGHT) /* ROW1, COL1 */
SW11: MATRIX_KEY(0x1, 0x2, KEY_LEFT) /* ROW1, COL2 */
SW12: MATRIX_KEY(0x2, 0x0, KEY_VOLUMEDOWN) /* ROW2, COL0 */
SW13: MATRIX_KEY(0x2, 0x1, KEY_VOLUMEUP) /* ROW2, COL1 */
