[PATCH 4/9] riscv: dts: microchip: add pci dma ranges for the icicle kit

Conor Dooley
2022-08-26T14:29:13Z

The recently removed, accidentally included, "matr0" property was used
in place of a dma-ranges property. The PCI controller is non-functional
with mainline Linux in the v2022.02 or later reference designs and has
not worked without configuration of address-translation since v2021.08.

Add the address translation that will be used by the v2022.09 reference
design & update the compatible used by the dts.
