[PATCH AUTOSEL 5.1 10/59] dmaengine: sprd: Fix the right place to configure 2-stage transfer

[Sasha Levin]

From: Eric Long <eric.long@xxxxxxxxxx>

[ Upstream commit c434e377dad1dec05cad1870ce21bc539e1e024f ]

Move the 2-stage configuration before configuring the link-list mode,
since we will use some 2-stage configuration to fill the link-list
configuration.
