FLEXCOM, among other functionalities, has the ability to offer the USART serial communication protocol. To have the FLEXCOM binding properly validate its USART children nodes, we must reference the correct binding. To differentiate between the SPI of FLEXCOM and the SPI of USART in SPI mode, use the clock-names property, since the latter's respective property is supposed to contain the "usart" string.
