[PATCH v1 4/6] dmaengine: dw-edma: Move HDMA_V0_MAX_NR_CH definition to edma.h

[Mrinmay Sarkar <quic_msarkar@quicinc.com>]

From: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org>

To maintain uniformity with eDMA, let's move the HDMA max channel
definition to edma.h. While at it, let's also rename it to HDMA_MAX_NR_CH.
