Add the device nodes for all SCIF and HSCIF serial ports on R-Car M3-W+.
Add the missing DMA properties to the already-present SCIF2 node.
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>

Tested with HSCIF1 on Salvator-XS.
To be queued in renesas-devel for v5.8.

Boot-testing the M3-W+ Salvator-XS on renesas-devel-2020-03-23-v5.6-rc7:
* before the patch, I get:
e6e88000.serial: ttySC0 at MMIO 0xe6e88000 (irq = 103, base_baud = 0) is a scif
* after the patch:
e6550000.serial: ttySC1 at MMIO 0xe6550000 (irq = 26, base_baud = 0) is a hscif
e6e88000.serial: ttySC0 at MMIO 0xe6e88000 (irq = 104, base_baud = 0) is a scif
