Instead of one function for each DLDO regulator, make 1 function that
takes an extra "index". Since the control bits for the DLDO regulators
are contiguous, this makes the function very simple. This removes a lot
of duplicate code.

by default and enable this option in defconfigs. CONFIG_DISPLAY
depends on CONFIG_I2C_EDID, so add and enable it in defconfigs, too.

The fuse status register provides the values from on-chip
voltage ID efuses programmed at the factory. These values
define the voltage requirements for the chip. u-boot reads
FUSESR and translates the values into the appropriate
commands to set the voltage output value of an external
voltage regulator.

BUILD_BUG_* macros have been defined in several headers. It would
be nice to collect them in include/linux/bug.h like Linux.
This commit is cherry-picking useful macros from include/linux/bug.h
of Linux 4.4.
I did not import BUILD_BUG_ON_MSG() because it would not work if it
is used with include/common.h in U-Boot. I'd like to postpone it
until the root cause (the "error()" macro in include/common.h causes
the name conflict with "__attribute__((error()))") is fixed.

It seems likely that at some point we will want a generic interrupt uclass.
But this is a big undertaking as it involves unifying code across multiple
architectures.
As a first step, create a simple IRQ uclass and a driver for x86. This can
be generalised later as required.
Adjust pirq_init() to probe this driver, which has the effect of creating
routing tables and setting up the interrupt routing. This is a start
towards making interrupts fit better with driver model.

A Platform Controller Hub is an Intel concept - it is like the peripherals

We have a very simple uclass to support PCHs. Add a few operations, such as
setting up the devices on the PCH and finding the SPI controller base
address. Also move it into drivers/pch/ since we will be adding a few PCH

Enable these devices using the VOPL video output device. We explicitly
disable VOPB in the device tree to avoid it taking over. Since this device
has an LCD display this comes up by default. If the display fails for some
reason then it will attempt to use HDMI. It is possible to force it to fail

rk_edp_probe(). For now there is no easy way to select between the two.

GPIO drivers want to be able to show if a pin is enabled for input, output,
or is being used by another function. Some drivers can easily find this
and the code is included in the driver. For some SoCs this is more complex.
Conceptually this should be handled by pinctrl rather than GPIO. Most
pinctrl drivers will have this feature anyway.
Add a method by which a GPIO driver can obtain the pin mux value given a
GPIO reference. This avoids repeating the code in two places.
