Since all the other call-sites of cros_ec_cmd_xfer() have been converted to use cros_ec_cmd_xfer_status() instead, update the remaining call-sites to prepare for the merge of cros_ec_cmd_xfer() into cros_ec_cmd_xfer_status(). As part of this update, change the error handling inside cros_ec_get_sensor_count() such that the legacy LPC interface is tried on all error values, not just when msg->result != EC_RESULT_SUCCESS. Note that there is a slight change in API in cros_ec_get_sensor_count(): it will return a negative number of sensors when there are no sensors on arm platform when MOTIONSENSE_CMD_DUMP is not supported (typical for sensorless chromebook) instead of 0. However, this is not a problem when probing the EC as we ignore errors only looking for cros_ec_get_sensor_count() returning a positive number of sensors.
