[PATCH v2 6/6] riscv: dts: allwinner: d1: Add SPI0 controller node

Some boards form the MangoPi family (MQ\MQ-Dual\MQ-R) may have
an optional SPI flash that connects to the SPI0 controller.

This controller is the same for R329/D1/R528/T113s SoCs and
should be supported by the sun50i-r329-spi driver.

So let's add its DT node.
