serial: pch_uart: revert Kconfig for non-DMA mode
PCH_DMA is not always enabled when a user uses PCH_UART. Since overhead of DMA is not small, in case of low frequent communication, without DMA is better. Thus, "select PCH_DMA" and DMADEVICES are unnecessary Signed-off-by: Tomoya MORINAGA <tomoya-linux@dsn.okisemi.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
