[PATCH] dmaengine: ti: k3-udma: Fix BCHAN count with UHC and HC channels

[Jai Luthra]

From: Vignesh Raghavendra <vigneshr@xxxxxx>

Unlike other channel counts in CAPx registers, BCDMA BCHAN CNT doesn't
include UHC and HC BC channels. So include them explicitly to arrive at
total BC channel in the instance.
