PCI: dwc: Skip finding eDMA channels count for HDMA platforms
In the case of Hyper DMA (HDMA) present in DWC controllers, there is no way the drivers can auto detect the number of read/write channels as like its predecessor embedded DMA (eDMA). So the glue drivers making use of HDMA have to pass the channels count during probe. To accommodate that, skip the existing auto detection of channels count procedure for HDMA based platforms. If the channels count passed by the glue drivers were wrong in any form, then the existing sanity check will catch it.
