dm: cros_ec: Convert to Kconfig

Browse Source 
Since both I2C and SPI are converted to Kconfig, we can convert cros_ec
to Kconfig for these buses.

LPC will need to wait until driver mode PCI is available.

config CROS_EC_KEYB
bool "Enable Chrome OS EC keyboard support"
help
Most ARM Chromebooks use an EC to provide access to the keyboard.
Messages are used to request key scans from the EC and these are
then decoded into keys by this driver.

config CMD_CROS_EC
bool "Enable crosec command"
depends on CROS_EC
help
Enable command-line access to the Chrome OS EC (Embedded
Controller). This provides the 'crosec' command which has
a number of sub-commands for performing EC tasks such as
updating its flash, accessing a small saved context area
and talking to the I2C bus behind the EC (if there is one).
config CROS_EC
bool "Enable Chrome OS EC"
help
Enable access to the Chrome OS EC. This is a separate
microcontroller typically available on a SPI bus on Chromebooks. It
provides access to the keyboard, some internal storage and may
control access to the battery and main PMIC depending on the
device. You can use the 'crosec' command to access it.
config CROS_EC_I2C
bool "Enable Chrome OS EC I2C driver"
depends on CROS_EC
help
Enable I2C access to the Chrome OS EC. This is used on older
ARM Chromebooks such as snow and spring before the standard bus
changed to SPI. The EC will accept commands across the I2C using
a special message protocol, and provide responses.
config CROS_EC_LPC
bool "Enable Chrome OS EC LPC driver"
depends on CROS_EC
help
Enable I2C access to the Chrome OS EC. This is used on x86
Chromebooks such as link and falco. The keyboard is provided
through a legacy port interface, so on x86 machines the main
function of the EC is power and thermal management.
config CROS_EC_SPI
bool "Enable Chrome OS EC SPI driver"
depends on CROS_EC
help
Enable SPI access to the Chrome OS EC. This is used on newer
ARM Chromebooks such as pit, pi and nyan-big. The SPI interface
provides a faster and more robust interface than I2C but the bugs
are less interesting.
config DM_CROS_EC
bool "Enable Driver Model for Chrome OS EC"
depends on DM
@ -5,5 +51,5 @@ config DM_CROS_EC
Enable driver model for the Chrome OS EC interface. This
allows the cros_ec SPI driver to operate with CONFIG_DM_SPI
but otherwise makes few changes. Since cros_ec also supports
I2C and LPC (which don't support driver model yet), a full
LPC (which doesn't support driver model yet), a full
conversion is not yet possible.
