Gabriel Somlo 7830e98785 lib: serial: fix RX path in litex-uart ...

When used to read characters from the terminal (e.g., when the SBI
console is used via ecall from linux with `console=hvc0`), we must
acknowledge receipt of each character to "pop" it off the LiteUART
hardware queue, and allow the next character to be made available.
