mfd: cros_ec: Sync to the latest cros_ec_commands.h from EC sources 

This just updates include/linux/mfd/cros_ec_commands.h to match the
latest EC version (which is the One True Source for such things).  See
<https://chromium.googlesource.com/chromiumos/platform/ec>

[dianders: took today's ToT version from the Chromium OS EC; deleted
references to cros_ec_dev and cros_ec_lpc since those aren't upstream
yet]

* Protocol overview
* Current version of this protocol
*
* request: CMD [ P0 P1 P2 ... Pn S ]
* response: ERR [ P0 P1 P2 ... Pn S ]
*
* where the bytes are defined as follow :
* - CMD is the command code. (defined by EC_CMD_ constants)
* - ERR is the error code. (defined by EC_RES_ constants)
* - Px is the optional payload.
* it is not sent if the error code is not success.
* (defined by ec_params_ and ec_response_ structures)
* - S is the checksum which is the sum of all payload bytes.
*
* On LPC, CMD and ERR are sent/received at EC_LPC_ADDR_KERNEL|USER_CMD
* and the payloads are sent/received at EC_LPC_ADDR_KERNEL|USER_PARAM.
* On I2C, all bytes are sent serially in the same message.
* TODO(crosbug.com/p/11223): This is effectively useless; protocol is
* determined in other ways. Remove this once the kernel code no longer
* depends on it.

* Byte codes returned by EC over SPI interface.
*
* These can be used by the AP to debug the EC interface, and to determine
* when the EC is not in a state where it will ever get around to responding
* to the AP.
*
* Example of sequence of bytes read from EC for a current good transfer:
* 1. - - AP asserts chip select (CS#)
* 2. EC_SPI_OLD_READY - AP sends first byte(s) of request
* 3. - - EC starts handling CS# interrupt
* 4. EC_SPI_RECEIVING - AP sends remaining byte(s) of request
* 5. EC_SPI_PROCESSING - EC starts processing request; AP is clocking in
* bytes looking for EC_SPI_FRAME_START
* 6. - - EC finishes processing and sets up response
* 7. EC_SPI_FRAME_START - AP reads frame byte
* 8. (response packet) - AP reads response packet
* 9. EC_SPI_PAST_END - Any additional bytes read by AP
* 10 - - AP deasserts chip select
* 11 - - EC processes CS# interrupt and sets up DMA for
* next request
*
* If the AP is waiting for EC_SPI_FRAME_START and sees any value other than
* the following byte values:
* EC_SPI_OLD_READY
* EC_SPI_RX_READY
* EC_SPI_RECEIVING
* EC_SPI_PROCESSING
*
* Then the EC found an error in the request, or was not ready for the request
* and lost data. The AP should give up waiting for EC_SPI_FRAME_START,
* because the EC is unable to tell when the AP is done sending its request.
