[PATCH v3 01/20] dmaengine: ti: k3-udma: Correct normal channel offset when uchan_cnt is not 0

[Peter Ujfalusi <peter.ujfalusi@ti.com>]

According to different sections of the TRM, the hchan_cnt of CAP3 includes
the number of uchan in UDMA, thus the start offset of the normal channels
are hchan_cnt.
