arm: spear13xx: Fix dmas cells
The "dmas" cells for the designware DMA controller need to have only 3 properties apart from the phandle: request line, src master and destination master. But the commit 6e8887f60f60 updated it incorrectly while moving from platform code to DT. Fix it. Cc: stable@vger.kernel.org # v3.10+ Fixes: 6e8887f60f60 ("ARM: SPEAr13xx: Pass generic DW DMAC platform data from DT") Reported-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Olof Johansson <olof@lixom.net>
