platform/chrome: cros_ec_proto: Introduce cros_ec_read_features helper
Extract the EC feature-reading logic from cros_ec_check_features() into
cros_ec_read_features() helper function.
Currently, cros_ec_check_features() swallows command transfer errors. By
isolating the transaction logic into an explicit helper that returns the
actual transfer error code, subsequent callers (such as the cros_ec_dev
driver during device probing) can catch a read error.
