ARM: dts: renesas: r9a06g032: Describe SPI controllers

Browse source

Add nodes for the 6 SPI controllers of the Renesas RZ/N1D SoC.
The first 4 can only be controllers, the latter 2 can only be targets.
DMA nodes are not added yet because DMA needs some extra code in the
drivers and cannot be tested yet.  Basic FIFO mode works reliably,
though.
