ARM: dts: imx53-qsb: Fix gpio button polarity
The polarity of the gpio buttons is defined to '0' which is active high. The buttons are active low though which has been verified by testing it and by looking into the schematics. While at it use defines rathers than numbers for the key codes. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
