[PATCH 0/2] Fixes for 3.8-rc1

These two patches are fixes needed for Linux 3.8.

The first patch fixes a lockup due to the missing SDIO clock. Since
the clkdev alias is missing, the sdio driver fails to
clk_prepare_enable() the clock. The lateinit call in the clk framework
then disables the clock since nobody owns it. The next access to the
SDIO register space causes the SoC to lockup.

The second patch fixes a null-pointer dereference. The conversion of
Kirkwood to pinctrl/gpio resulted in that using GPIO calls inside the
board-*.c file causes an exception, since the gpio driver has not yet
been loaded. Topkick is using the GPIO to control power to the SATA0
device. So convert the gpio to a fixed regulator, in DT, which gets
loaded after the gpio driver is available.

  ARM: Kirkwood: Use fixed-regulator instead of board gpio call
