[PATCH 4.9 055/130] dmaengine: pl330: report BURST residue granularity

[Greg Kroah-Hartman]

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

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

From: Marek Szyprowski <m.szyprowski@xxxxxxxxxxx>

[ Upstream commit e3f329c600033f011a978a8bc4ddb1e2e94c4f4d ]

The reported residue is already calculated in BURST unit granularity, so
advertise this capability properly to other devices in the system.
