In 4a3956d7 (drivers/intel/gma, soc/intel/common: improve
cooperation) the vbt_size parameter was not honored leading to
the use of unitialized variables from the caller. Instead, keep
track of if the vbt is already loaded by using the size returned
from the load. If it's non-zero the vbt has been loaded.

Instead of both featuring their own VBT loaders, use a single one.
It's the compression-enabled one from soc/intel/common, but moved to
drivers/intel/gma.
The rationale (besides making all the Kconfig fluff easier) is that
drivers/intel/gma is used in some capacity on all platforms that load a
VBT, while soc/intel/common's VBT code is for use with FSP.

TEST=GOOGLE_FALCO and GOOGLE_CHELL both build, exercising both affected

Most Intel platforms use separate registers for software-based
SMI (0xe0) and SCI (0xe8), but Atom-based platforms use a single
combined register (0xe0) for both. Adjust opregion implementation
to use the correct register for Atom-based platforms.
Test: Boot Windows on Atom-based ChromeOS device with Tianocore
payload and non-VBIOS graphics init; observe Intel display
driver loaded correctly and internal display not blank.
(requires additional change for Atom platforms to select
CONFIG_INTEL_GMA_SWSMISCI)

Although Intel's current spec[1] shows the OpRegion structure version
as being the top 16 bits of the field, Intel's Windows drivers
require the OpRegion structure version to be in the top 8 bits of
the field when not using a VGA BIOS (eg, NGI or GOP driver).
As the Linux i915 driver only checks that the version is >= 2,
there is no change in functionality there.
This change effectively matches Intel's implementation in TianoCore,
where the version is set to 0x0200 << 16.

TEST: Boot Windows [8.1,10] in UEFI mode w/GOP graphics init and
Legacy mode with libgfxinit, observe Intel GPU driver functional.

Add a new common method to initialize ACPI OpRegion.
* Try to locate vbt.bin in CBFS.
* Try to locate VBIOS in CBFS.
* Keep existing code to probe at 0xc0000.
Tested on Lenovo T430 (sandybridge) using vbt.bin, tested using buggy
VBIOS with wrong vbt_offset, tested with fake vbt written by NGI at
0xc0000.
Tested with https://review.coreboot.org/#/c/21766/ on i945 (using fake
vbt at 0xc0000), x4x (using vbt.bin) and gm45 (using vendor VBIOS).
In all cases linux was successfully provided with VBT from ACPI
opregion.

Migrate opregion code from northbridge/intel/common to
drivers/intel/gma in preparation for consolidation with
soc/intel/common opregion code. Rename init_igd_opregion()
for clarity and disambiguation with other implementations.
