PCI: endpoint: pci-epf-{mhi/test}: Move DMA initialization to EPC init callback

Browse source

To maintain uniformity across EPF drivers, move DMA initialization to EPC
init callback. This will also allow us to deinit DMA during PERST# assert
in the further commits.

For EPC drivers without PERST#, DMA deinit will only happen during driver
unbind.
