Subject[PATCH 1/3] platform/chrome: Move cros-ec transport drivers to drivers/platform.
Date
There are some cros-ec transport drivers (I2C, SPI) living in MFD, while
others (LPC) living in drivers/platform. The transport drivers are more
platform specific. So, move the I2C and SPI transport drivers to the
platform/chrome directory. The patch also removes the MFD_ prefix of
their Kconfig symbols.

You also need to enable the driver for the bus you are using. The
