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.
