George G. Davis 3078e80b03 serial: sh-sci: disable DMA for uart_console ...

commit 099506cbbc upstream.

As noted in commit 84b40e3b57 ("serial: 8250: omap: Disable DMA for
console UART"), UART console lines use low-level PIO only access functions
which will conflict with use of the line when DMA is enabled, e.g. when
the console line is also used for systemd messages. So disable DMA
support for UART console lines.
