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.
