Apparently, if G3D regulator is powered off, the SoC cannot enter low
power modes and just hangs. This patch fixes this by keeping the
regulator always on when the system is running, as suggested by Exynos 4
User's Manual in case of Exynos4210/4x12 SoCs (Exynos5250 UM does not
have such note, but observed behavior seems to confirm that it is true
for this SoC as well).

This fixes an issue preventing Arndale board from entering sleep mode
observed since commit

346f372f clk: exynos5250: Add CLK_IGNORE_UNUSED flag for pmu clock

that landed in kernel 3.10, which has fixed the clock driver to make the
SoC actually try to enter the sleep mode.

Rather than requiring each board to explicitly disable the SPI controllers
it is not using instead require boards to enable those that they are using.
This is less work overall since normally at most one of the controllers is
in use and avoids issues caused by inappropriate pinmuxing.

For consistency and correctness, since this is a bus, even if not

The Arndale has a SMSC USB3503 connected in hardware only mode like a PHY,
support it using the usb-nop-xceiv binding.

Note that due to a regrettable decision to use a regulator to represent
the reset signal this uses a fixed voltage regulator to do that, there
is a plan to use the reset controller binding once that is merged so it
does not seem worthwhile to fix the usb-nop-xceiv driver at this point.
