For the most part, the SDHI controller in the RZ/A1 (r7s72100) is the same as other Renesas SoC...except for the fact that the data port register was widened to 32-bits and the 16-bit accesses in the current tmio driver aren't going to cut it. Also, the tmio driver allows you to pass in what voltages you support via the ocr_mask. For the RZ/A1, it's just simple 3.3v. So, I added the ability to pass that when using DT.
