For DMA initialization to work across all EPC drivers, the DMA initialization has to be done in the .init() callback.
This is because not all EPC drivers will have a refclock (which is often needed to access registers of a DMA controller embedded in a PCIe controller) at the time the .bind() callback is called.
However, all EPC drivers are guaranteed to have a refclock by the time the .init() callback is called.
Thus, move the DMA initialization to the .init() callback.
This change was already done for other EPF drivers in commit 60bd3e039aa2 ("PCI: endpoint: pci-epf-{mhi/test}: Move DMA initialization to EPC init callback").

Looks good.
