This patch series aims to add DMA support for SCIFA/ SCI TX support on
RZ/G2L alike SoCs.

v2->v3:
 * Dropped inline function is_rz_scif_port() and instead using
   s->cfg->regtype == SCIx_RZ_SCIFA_REGTYPE for finding RZ SCIF port.
 * Dropped SCIx_TEI_IRQ as DMAC activation not possible with TEI interrupt.
 * Updated the code flow similar to SCIFA/SCIFB DMAC tx handling.
 * Replaced is_rz_scif_port to s->cfg->regtype check
 * Updated the code flow similar to SCIFA/SCIFB DMA rx handling.
 * Added remaining patches from Renesas SCI fixes patch series to this series.
 * Updated commit description for patch#3
 * Moved handling of clearing TE bit as separate patch#5.
v1->v2:
 * Added support for DMA tx and rx.
