Linux kernel expects that power management with ACPI should always be

decide whether the device loses power in suspend. Thus, until the kernel
has a better way for drivers to query if device lost power in suspend,
we need to allow passing in of GPIOs via _CRS as well as exporting

clean up the interface to SPI used by flash.
Flash uses a command-response kind of communication. Thus, even though
SPI is duplex, flash command needs to be sent out on SPI bus and then
flash response should be received on the bus. Some specialized x86
flash controllers are capable of handling command and response in a
single transaction.
In order to support all the varied cases:
1. Add spi_xfer_vector that takes as input a vector of SPI operations
and calls back into SPI controller driver to process these operations.
2. In order to accomodate flash command-response model, use two vectors
while calling into spi_xfer_vector -- one with dout set to
non-NULL(command) and other with din set to non-NULL(response).
3. For specialized SPI flash controllers combine two successive vectors
if the transactions look like a command-response pair.
4. Provide helper functions for common cases like supporting only 2
vectors at a time, supporting n vectors at a time, default vector
operation to cycle through all SPI op vectors one by one.

Combine existing boards google/auron_paine and google/samus with new
ChromeOS devices auron_yuna, gandof and lulu, using their common
reference board (auron) as a base.
Chromium sources used:
firmware-yuna-6301.59.B 6ed8b9d [CHERRY-PICK: broadwell: Update to...]
firmware-gandof-6301.155.B 666f34f [gandof: modify power limiting for...]
firmware-lulu-6301.136.B 8811714 [lulu: update RAMID table]
Additionally, some minor cleanup/changes were made:
- I2C devices set to use level (vs edge) interrupt triggering
- HDA verb entries use simplified macro entry format
- correct FADT table header version
- remove unused ACPI device entries / .asl file(s)
- clean up ACPI code (e.g., trackpad on Lulu)
- adjust _CID for trackpad on Lulu in order to not load non-functional
Windows driver (does not affect Linux)
- remove unused header includes (multiple/various)
- correct I2C addresses used for SMBIOS device entries
- correct misc typos etc
The existing auron_paine samus boards are removed.
Variant setup modeled after google/slippy
