Enric Balletbo i Serra cc8a4ea182 platform/chrome: Move mfd/cros_ec_lpc* includes to drivers/platform.
The cros-ec-lpc driver lives in drivers/platform because is platform
specific, however there are two includes (cros_ec_lpc_mec.h and
cros_ec_lpc_reg.h) that lives in include/linux/mfd. These two includes
are only used for the platform driver and are not really related to the
MFD subsystem, so move the includes from include/linux/mfd to
drivers/platform/chrome.

Shawn Nematbakhsh 8d4a3dc423 platform/chrome: cros_ec_lpc: Add support for mec1322 EC
This adds support for the ChromeOS LPC Microchip Embedded Controller
(mec1322) variant.

mec1322 accesses I/O region [800h, 9ffh] through embedded memory
interface (EMI) rather than LPC.
