serial: sh-sci: Make RX/TX DMA function names consistent
Most RX/TX-specific DMA functions are prefixed with "sci_dma_[rt]x_". Rename the exceptions to increase consistency. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Reviewed-by: Simon Horman <horms+renesas@verge.net.au> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
