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.

0-byte writes can be used as a way to probe/check presence of an i2c
device, so adjust _dw_i2c_transfer() to immediately set the STOP bit
and raise logger level for TX abort messages when the segment length
is zero. Adjust dw_i2c_transfer() to allow zero-segment-length
messages to be passed thru to _dw_i2c_transfer().
Tested as part of entire i2c-detect patch train.

After commit ae48b42683 (payloads/tianocore: Init submodules),
Tianocore's Makefile no longer detects an unclean working directory and
thus always performs a `git checkout`, overwriting any uncommited
changes made in the cloned sources.
The change of "clean" to "dirty" effectively inverts the logic of the
if-else condition, which would normally swap the two possible code paths
of the branch. However, since `git status` outputs multiple lines, most
of which do not contain "clean", the -v option (select non-matching
lines) causes grep to always match at least 1 line and thus return
success. This causes the if-else branch containing the `git checkout`
to always be taken regardless of the state of the working tree, masking
the issue of the inverted logic. Removing the -v option addresses both
of these issues and restores the intended behavior of the if-else block.
TEST:
1) Build coreboot successfully with the Tianocore UefiPayloadPkg option.
2) Make a change in the cloned Tianocore sources that results in an
unclean working directory and check for the "Working directory not
clean" message when building coreboot.
