spi: sunxi: Add support for R329/D1/R528/T113 SPI controller

These SoCs have two SPI controllers that are quite similar to the SPI
on previous Allwinner SoCs. The main difference is that new SoCs
don't have a clock divider (SPI_CCR register) inside SPI IP.

Instead SPI sample mode should be configured depending on the input clock.

For now SPI input clock source selection is not supported by this driver,
and only HOSC@24MHz can be used as input clock. Therefore, according to
the, manual we could change the SPI sample mode from delay half
cycle(default) to normal.

This patch adds a quirk for this kind of SPI controllers
