Add support for UniPhier external DMA controller (XDMAC), that is
implemented in Pro4, Pro5, PXs2, LD11, LD20 and PXs3 SoCs.
Changes since v3:
- dt-bindings: Fix typo
Changes since v2:
- dt-bindings: Fix SPDX and some properties
- Fix iteration count calculation for memcpy
- Replace zero-length array with flexible-array member in struct
uniphier_xdmac_device.
Changes since v1:
- dt-bindings: Rewrite with DT schema.
- Change return type of uniphier_xdmac_chan_init() to void,
and remove error return in probe.
