[PATCH 1/5] PCI: dwc: Fix eDMA mapping info string

[Serge Semin]

DW PCIe controller can be equipped with the next types of DMA controllers:
1. eDMA controller with viewport-based CSRs access (so called legacy),
2. eDMA controller with unrolled CSRs mapping,
3. HDMA controller compatible with the eDMA unrolled CSRs mapping,
4. HDMA controller with native CSRs mapping.
The later three types imply having the DMA-engine CSRs _unrolled_ mapping.
Let's fix the info-message printed in the DW PCIe eDMA controller
detection procedure to comply with that.
