spi: sun6i: add support for R329/D1/R528/T113s SPI controllers
These SoCs has two SPI controllers. One of it is quite similar to previous ones, but with internal clock divider removed; the other added MIPI DBI Type-C offload based on the first one. Add basical support for these controllers. As we're not going to support the DBI functionality now, just implement the two kinds of controllers as the same.
