IPQ5018 uses Qualcomm QCE crypto engine v5.1 which is already supported.
So let's add the dts nodes for its DMA v1.7.4 and QCE itself.

Changes in v2:
- As per Konrad's comment, the BAM DMA controller is v1.7.4, so updated
  the dma controller node accordingly.
- Link to v1: https://lore.kernel.org/r/20250523-ipq5018-crypto-v1-1-0818047d8a18@outlook.com
