The SOCFPGA dev kit was hanging during bootup on the SD/MMC driver loading.
The first patch fixes the booting and the 2nd patch adds a regulator node
for the SD/MMC driver to use.

v4 diff(s):
- Add a new patch to rename the GPIO IP DTS node
- Use &gpio1 to set status="okay"
- Update the cd-gpios to use &portb

v3 diff(s): Thanks to Doug Anderson, the real issue was that the GPIO bank used
by cd-gpios did not have status="okay" in the node. This cause the GPIO to not
get probed correctly.

In fact, prior to patch 3cf890fc42b "mmc: dw_mmc: Pass back errors from
mmc_of_parse()", the error was being masked, so it was not being detected.

v2 diff(s): Patch 2/2 ARM: dts: socfpga: Add a 3.3V fixed regulator node
        - Move the regulator nodes to their respective board dts file and
          correctly rename the regulator to match the schematic

Dinh Nguyen (3):
  ARM: dts: socfpga: rename gpio nodes
  ARM: dts: socfpga: Fix SD card detect
  ARM: dts: socfpga: Add a 3.3V fixed regulator node
