7e6343ef94 x86: acpi: Clean up table header revisions
The comment of initializing table header revision says:

    /* ACPI 1.0/2.0: 1, ACPI 3.0: 2, ACPI 4.0: 3 */

which might mislead it may increase per ACPI spec revision.
However this is not the case. It's actually a fixed number
as defined in ACPI spec, and in the laest ACPI spec 6.1,
some table header revisions are still 1. Clean these up.

8a8c035255 x86: acpi: Various changes to acpi_table.h
- Use "U-BOOT" and "U-BOOTBL" for the OEM ID and OEM table ID.
- Do not typedef acpi_header_t, instead use struct acpi_table_hader.
- Use a shorter name aslc_id and aslc-revision.
- Change MCFG base address to use 32-bit value pairs (_l and _h).
- Apply ACPI_APIC_ prefix to MADT APIC type macros and make
  their names to be more readable.
- Apply __packed to struct acpi_madt_irqoverride and struct
  acpi_madt_lapic_nmi tables, as they are not naturally aligned
  by the compiler which leads to wrong sizeof(struct).
- Rename model to res1 as it is reserved after ACPI spec 1.0.
- Apply ACPI_ prefix to the PM profile macros and change them
  to enum.
- Add ospm_flags to FACS structure which is defined since ACPI 4.0.

7ac99be6e2 x86: Add an ICH6 pin configuration driver
Add a driver which sets up the pin configuration on x86 devices with an ICH6
(or later) Platform Controller Hub.

The driver is not in the pinctrl uclass due to some oddities of the way x86
devices work:

- The GPIO controller is not present in I/O space until it is set up
- This is done by writing a register in the PCH
- The PCH has a driver which itself uses PCI, another driver
- The pinctrl uclass requires that a pinctrl device be available before any
other device can be probed

It would be possible to work around the limitations by:
- Hard-coding the GPIO address rather than reading it from the PCH
- Using special x86 PCI access to set the GPIO address in the PCH

However it is not clear that this is better, since the pin configuration
driver does not actually provide normal pin configuration services - it
simply sets up all the pins statically when probed. While this remains the
case, it seems better to use a syscon uclass instead. This can be probed
whenever it is needed, without any limitations.

Also add an 'invert' property to support inverting the input.

fa287b1580 x86: qemu: add the ability to load and link ACPI tables from QEMU
This patch adds the ability to load and link ACPI tables provided by QEMU.
QEMU tells guests how to load and patch ACPI tables through its fw_cfg
interface, by adding a firmware file 'etc/table-loader'. Guests are
supposed to parse this file and execute corresponding QEMU commands.

e5ffa4bb62 x86: queensbay: Really disable IGD
According to Atom E6xx datasheet, setting VGA Disable (bit17)
of Graphics Controller register (offset 0x50) prevents IGD
(D2:F0) from reporting itself as a VGA display controller
class in the PCI configuration space, and should also prevent
it from responding to VGA legacy memory range and I/O addresses.

However test result shows that with just VGA Disable bit set and
a PCIe graphics card connected to one of the PCIe controllers on
the E6xx, accessing the VGA legacy space still causes system hang.
After a number of attempts, it turns out besides VGA Disable bit,
the SDVO (D3:F0) device should be disabled to make it work.

To simplify, use the Function Disable register (offset 0xc4)
to disable both IGD (D2:F0) and SDVO (D3:F0) devices. Now these
two devices will be completely disabled (invisible in the PCI
configuration space) unless a system reset is performed.
