ARM: dts: socfpga: Fix SD card detect

Browse Source 
Without this patch, the booting the SOCFPGA platform would hang at the
SDMMC driver loading. The issue, debugged by Doug Anderson, turned out
to be that the GPIO bank used by the SD card-detect was not set to
status="okay".

Also update the cd-gpios to point to portb of the &gpio1 GPIO IP.

v3: Correctly degugged the issue to be a gpio node not having status="okay"
