ARM: dts: msm: Update DDR bandwidth for sun GMU scaling

Browse Source 
SVS is the highest voltage corner for GMU. The lowest DDR BW
that puts CX at SVS corner is 1555 MHz. This DDR vote puts CX
at a corner high enough such that GMU can run at 650 MHz. This
is to get better GMU performance at no extra power cost.
