Switch to using the common MEC interface instead of the
Chrome EC specific code.
Tested on a Chell chromebook that has a MEC based Chrome EC
to ensure that the EC interface is still functional.

Instead of defining the same functions for reading/clearing boot-mode
switches from EC in every mainboard, add a common infrastructure to
enable common functions for handling boot-mode switches if
GOOGLE_CHROMEEC is being used.
Only boards that were not moved to this new infrastructure are those
that do not use GOOGLE_CHROMEEC or which rely on some mainboard specific
mechanism for reading boot-mode switches.

In some cases, we don't want the Chrome EC firmwares (both EC and PD)
built directly by the coreboot build system or included in images at
all. This is already supported with EC_EXTERNAL_FIRMWARE but it does
implement a binary (build and include) or (neither build nor include)
policy.
Some cases require the ability to separately control whether the EC
and PD firmwares should be built and included by the coreboot build
system, only included from externally-built images or not included
at all.
This introduces config changes implementing that behaviour, renaming
options to make it clear that they are specific to the Chrome EC.

The Chrome OS bootloader is changing its EC software sync mechanism to
look for the hash of an EC image in a separate CBFS file, rather than
using the CBFS hash attribute of the image itself (see
http://crosreview.com/348061). This patch makes coreboot generate
appropriate hash files for the new format when it builds and bundles a
Chrome EC image. This also allows us to compress the EC image itself.

This change switches all ECs and the generic EC ACPI code
to be autoincluded by Makefile.inc, rather than having to be
mentioned explicitly in ec/Makefile.inc or in
ec/<vendor>/Makefile.inc.
This means, vendor and ec directories are now "drop
in", e.g. be placed in the coreboot directory hierarchy
without having to modify any higher level coreboot files.
The long term plan is to enable out of tree components to be
built with a given coreboot version (given that the API did not
change).

Since EC protocol v3, the packet format will be the same for all buses (inclding

To prepare for that, we will move the protocol part into crosec_proto.c:
crosec_command_proto, with bus driver in callback "crosec_io".

The Chrome EC can be connected by different types of bus like LPC / I2C / SPI,
and the current implementation is only for LPC.
To support other types, we must first isolate the LPC protocol stuff and add
configuration variable (EC_GOOGLE_CHROMEEC_LPC) to specify bus type.
Verified by building google/link (with chromeec) configuration successfully.
