Javier Martinez Canillas 97372e5a99 clk: exynos5420: Restore GATE_BUS_TOP on suspend 
Commit ae43b32891 ("ARM: 8202/1: dmaengine: pl330: Add runtime Power
Management support v12") added pm support for the pl330 dma driver but
it makes the clock for the Exynos5420 MDMA0 DMA controller to be gated
during suspend and this in turn makes its parent clock aclk266_g2d to
be gated. But the clock needs to be ungated prior suspend to allow the
system to be suspend and resumed correctly.

Add GATE_BUS_TOP register to the list of registers to be restored when
the system enters into a suspend state so aclk266_g2d will be ungated.

Thanks to Abhilash Kesavan for figuring out that this was the issue.
