cros_ec: Clean up multiple EC protocol support
Version 1 protocols (without command version) were already no longer
supported in cros_ec.c. This removes some dead code from the
cros_ec_i2c driver.
Version 2 protcols (with command version) are now called
protocol_version=2, instead of cmd_version_is_supported=1.
A subsequent change will introduce protocol version 3 for SPI.
