arm: sama5: sam_serial: fix to compile with "UART Flow control enabled" on
SAMA5D2.
SAMA5D2 has UART (TX/RX only) and FLEXCOM USART (with control pins).
UART has only TX/RX, so if I try to use flow control with FLEXCOM USART,
there is no register definition on the UART side and get a compilation
error.
