[ARM] pxa/pcm990: start external GPIOs immediately after built-in ones
As a result of an off-by-1 error pcm990 leaves one unused GPIO number between built-in GPIOs and the pca9536 extender. Fix it. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Eric Miao <eric.miao@marvell.com>
