This patch implements a SoC overrides to set CPU privilege level
as the MSR is not consistent across platforms. For example:
On APL/GLK/DNV, it's MSR 0x120 and CNL onwards it's MSR 0x151.

The Intel Firmware Interface Table (FIT) is a bit of an annoying outlier
among CBFS files because it gets manipulated by a separate utility
(ifittool) after cbfstool has already added it to the image. This will
break file hashes created for CBFS verification.
This is not actually a problem when booting, since coreboot never
actually loads the FIT from CBFS -- instead, it's only in the image for
use by platform-specific mechanisms that run before coreboot's
bootblock. But having an invalid file hash in the CBFS image is
confusing when you want to verify that the image is correctly built for
verification.
This patch adds a new CBFS file type "intel_fit" which is only used for
the intel_fit (and intel_fit_ts, if applicable) file containing the FIT.
cbfstool will avoid generating and verifying file hashes for this type,
like it already does for the "bootblock" and "cbfs header" types. (Note
that this means that any attempt to use the CBFS API to actually access
this file from coreboot will result in a verification error when CBFS
verification is enabled.)

There are too many "FIT" in firmware land. In order to reduce possible
confusion of CBFS_TYPE_FIT with the Intel Firmware Interface Table, this
patch renames it to CBFS_TYPE_FIT_PAYLOAD (including the cbfstool
argument, so calling scripts will now need to replace `-t fit` with `-t
fit_payload`).

Add 'detect' flag which can be attached to devices which may or may not
be present at runtime, and for which coreboot should probe the i2c bus
to confirm device presence prior to adding an entry for it in the SSDT.
This is useful for boards which may utilize touchpads/touchscreens from
multiple vendors, so that only the device(s) present are added to the
SSDT. This relieves the burden from the OS to detect/probe if a device
is actually present and allows the OS to trust the ACPI _STA value.

This patch adds the I2C equivalent of an SMBus quick write to an I2C
device, which is used by some I2C drivers as a way to probe the
existence (or absence) of a certain device on the bus, based on
whether or not a 0-byte write to an I2C address is ACKed or NACKed.
i2c_dev_detect() is implemented using the existing i2c bus ops transfer()
function, so no further work is needed for existing controller drivers
to utilize this functionality.
