riscv: dts: allwinner: d1: Add SPI controllers 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 nodes.
