Biju Das 8749061be1 tty: serial: sh-sci: Add RZ/G2L SCIFA DMA tx support 
SCIFA IP on RZ/G2L SoC has the same signal for both interrupt
and DMA transfer request. Setting DMARS register for DMA transfer
makes the signal to work as a DMA transfer request signal and
subsequent interrupt requests to the interrupt controller
are masked. Similarly clearing DMARS register makes signal to work as
interrupt signal and subsequent interrupt requests to the interrupt
controller are unmasked.

Add SCIFA DMA tx support for RZ/G2L alike SoCs by disabling TXI line
interrupt and setting DMARS registers by DMA api for DMA transfer request.
