Subject: [PATCH 4.5 187/200] ARM: dts: pxa: fix dma engine node to pxa3xx-nand

4.5-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Robert Jarzmik <robert.jarzmik@...e.fr>

commit 07c6b2d01d351f0512ed7145625265e435ab3240 upstream.

Since the switch from mmp_pdma to pxa_dma driver for pxa architectures,
the pxa_dma requires 2 arguments, namely the requestor line and the
requested priority.

Fix the only left device node which was still passing only one argument,
making the pxa3xx-nand driver misbehave in a device-tree configuration,
ie. failing all data transfers.

Fixes: c943646d1f49 ("ARM: dts: pxa: add dma engine node to pxa3xx-nand")
