mfd: at91-usart: Do not use compatible to register child devices
There are no separate serial/SPI devices under the at91-usart MFD, but actually the MFD is used as a serial or a SPI device. There are no DT sub-nodes for the MFD children, so we should use platform device API to register the drivers.
