It has been observed on a number of platforms (baytrail, kaby lake)
that if serial console is not enabled in coreboot, but is enabled in
kernel (v4.4), then on resume kernel hangs. In order to fix this, add
support for enabling UART debug port controller on resume.
In order to decide whether UART debug port controller should be
enabled in ramstage, following things are checked in given order:
1. If coreboot has serial console enabled, there is no need to
re-initialize the controller.
2. This special action is taken only for UART debug port controller.
3. If boot is not S3 resume, then initialization is skipped.
4. Callback into SoC to check if it wants to initialize the
controller.
If all the above conditions are met, then UART debug port controller
is initialized and taken out of reset.
BUG=b:64030366
TEST=Verified with the entire patchset series that:
1. If coreboot does not have serial console enabled, but Linux kernel
has console enabled, then on resume, coreboot initializes UART debug
port controller.
2. If coreboot and Linux do not have serial console enabled, then
coreboot does not initialize UART debug port controller.
3. If coreboot has serial console enabled, there is no change in
behavior.

Get rid of old hybrid graphics driver and use the new one.
1. Disable IGD and PEG in early romstage.
The PEG port will get disabled on devices that do not have a
discrete GPU. The power savings are around ~1Watt.
The disabled IGD does no longer waste GFX stolen memory.
2. Get rid of PCI driver
The Nvidia GPU can be handled by the generic PCI driver and allows
to use the ACPI _ROM generator for Switchable graphics.
3. Settings are stored in devicetree.
One driver for all Lenovo hybrid graphics capable devices.
4. Add support for Thinker1 GPU power handling.
Only boards that do use reference design 2012 are known to be
supported. Needs test on boards that do you use reference design 2013.

Introduce a chip_driver that uses devicetree instead of Kconfig.
The new driver has the following advantages:
* No more wasted IGD GFX stolen memory
* Can be used by T500 series
* Is even run on devices that do not have a dGPU installed
* Can disable unused PEG port on devices without dGPU (and save power)
* Use devicetree instead of Kconfig options
* Support for multiple hybrid GPIO active levels
* Support for backlight control GPIO
* Support for _ROM on Optimus capable devices
The driver is split into romstage part and ramstage part.
Every mainboard has to call the driver in romstage to get the requested
GPU state. The mainboard code then has to toggle GPU power or disable
the IGD or PEG port.
The ramstage part does handle the hygrid graphics GPIO, including
optional backlight mux GPIO. Every GPIO can have it's own active level,
as defined in devicetree. Devices are no longer disabled in ramstage.
The existing hybrid graphics driver does the same configuration and
should not interfere with this commit until it has been removed.

This mainboard features is an G43 northbridge, ICH10 southbridge and
Winbond W83627dhg SuperI/O. This board is impossible to flash
internally with vendor bios (BIOS region is WP and other regions like
IFD and ME are read only and inaccessible respectively). Due to either
ICH10 or board layout it is also impossible to do ISP, which requires
desoldering flash chip. To make hacking more easy there is an empty
SPI header next to spi flash pads which can be hooked up to a SPI
flash.
What works:
* 2 DDR2 dimms per channel (tested with 1+2G in CH0 and 2+2G in CH1);
* SATA with AHCI
* Integrated GPU with option rom (extracted from a Gigabyte vendor
bios)
* VGA (on DVI) with NGI if patched to use DVI gmbus port for output
* PCI
* Reboot and S3 resume
* Descriptor mode with ME disable straps and ME region absent (no
working gbe in this configuration though)
* USB.
What does not work:
* GBE (probably requires working ME);
* Analog on DVI port out is shaking, which is not the case with vendor
BIOS (setting clockgen on smbus 0x69 like vendor fixes it).
* Booting with ME enabled (needs raminit patches for that)
Not tested:
* Sound;
* All the rest.
Not coreboot related problems:
* Flashing this board with vendor bios is a PITA and requires
desoldering flash chip;
* In situ programming is not possible.

Uses common hardware access functions to make smbus block read and
write available in romstage.
Those are needed to reconfigure the clockgen on smbus offset 0x69,
which is sometimes needed for things like CPU C-states or analog
display out to work properly.

All Intel southbridges implement the same SMBus functions.
This patch replaces all these similar and mostly identical
implementations with a common file.
This also makes i2c block read available to all those southbridges.
If the northbridge has to read a lot of SPD bytes sequentially, using
this function can reduce the time being spent to read SPD five-fold.
