[PATCH v3 1/4] arm64: dts: socfpga: agilex5: add FPGA manager and region nodes

[Adrian Ng Ho Yin <adrian.ho.yin.ng@altera.com>]

Add the fpga-mgr child node under the svc firmware node and a fpga-region
node to enable FPGA configuration and partial reconfiguration on Agilex5.

The SMMU is already enabled upstream; it remains a hard requirement for
the svc driver to allocate DMA buffers within the SDM-accessible address
range.
