Add support for accessing GPIOs using of-plata. This uses the same
mechanism as for clocks, but allows use of the xlate() method so that
the driver can interpret the parameters.
Update the condition for GPIO_HOG so that it is not built into SPL,
since it needs SPL_OF_REAL which is not enabled in sandbox_spl.

This patch adds a limited pulse-width modulator to sandbox's Chromium OS
Embedded Controller emulation. The emulated PWM device supports multiple
channels but can only set a duty cycle for each, as the actual EC
doesn't expose any functionality or information other than that. Though
the EC supports specifying the PWM channel by its type (e.g. display
backlight, keyboard backlight), this is not implemented in the emulation
as nothing in U-Boot uses this type specification.
This emulated PWM device is then used to test the Chromium OS PWM driver
in sandbox. Adding the required device node to the sandbox test
device-tree unfortunately makes it the first PWM device, so this also
touches some other tests to make sure they still use the sandbox PWM.

A sandbox driver and test are added for the qfw uclass, and a test in
QEMU added for qfw functionality to confirm it doesn't break in real
world use.

Move sandbox_spl over to use OF_PLATDATA_INST. Create a new board to
test the case when this is not enabled, since we will be keeping that
code around for several months and want to avoid regressions.
Skip the dm_test_of_plat_dev() test since driver info is not available
for OF_PLATDATA_INST.
