cd7bb2faab slippy: Enable EC SMI
Enable GPIO SMI for GPIO34 and set it as inverted so it
is only generated when it is raised by the EC.

1) ec console command: lidopen
2) wait until booted to developer screen
3) ec console command: lidclose
4) ensure system turns off

d7cb8d074f lynxpoint: Change SerialIO device enable reporting to ACPI
In order to report whether coreboot enabled a SerialIO device
in ACPI mode we had been relying on reading NVS in the _STA
method for the SerialIO device.

The ACPI _STA method has restrictions on what it can access
and is unable to access OperationRegions outside its scope
which means it should not be trying to read NVS.

This change adds a new SSDT to the ACPI tables and fills it
with constants that indicate whether or not a device is enabled
in ACPI mode.

The ACPI code is changed to read these variables from the
SSDT and use that instead of trying to query a variable in NVS.

Attempt to use lpt-clk driver to probe the
device clocks for SerialIO devices and see that the kernel
does not complain about accessing the GNVS region.

the pointer to the memory console directly in a field named 'CBMC'.
This field lives in the GNVS table.

fe8290de22 Fix VGA option rom INT15 handler
The format of this function changed but was not updated in
all mainboards.  This fixes all Sandybridge/Ivybridge boards.
The int15 handler no longer takes a regs structure as an
argument and instead uses global variables.  The yabel interface
is now similar enough that we can drop the duplicate handler.

While things appeared to work, there were actually invalid references
to CAR storage after CAR was torn down on boards without
EARLY_CBMEM_INIT. It was discussed use of CAR_GLOBAL should be
restricted to boards that handle CAR migration properly.

d686acd1a3 pit: Redo the display port bridge initialization code.
The display port bridge on pit is different from the one on snow and needs to
be initialized differently. Instead of waiting for the chip to come up on its
own and assert the hotplug detect, we need to access it over i2c and get it up
and running ourselves.

c0b2144f69 pit: Replace the tps65090 functions and adjust the hotplug detect line.
The functions which manipulated the tps65090 were removed a while ago because
it isn't accessible directly from the AP, it's on an I2C bus that has to be
accessed by the EC on our behalf. Now that that capability has been added, we
can rewrite the small portion of the the tps65090 we actually used but using
the EC passthrough commands.

Also, we should not be configuring the hardware display port hotplug detect
line since we're using it as a GPIO for other purposes. The GPIO we're using
instead defaults to being an input, but to be safe we should probably
explicitly configure it as one anyway.
