If we have control over the LDO then disable it during suspend; the device is already being put into reset so will be non-functional over suspend anyway and this will save a small amount of power.

On Tegra Beaver and Dalmore boards. As you may have noticed, Tegra audio doesn't work after resume at the moment, but that's true irrespective of these patches, and I believe is a problem without our DMA or I2S drivers, and nothing to do with the CODEC. The CODEC certainly still responds to I2C accesses (e.g. triggered by alsamixer) after this patch, and wouldn't if the LDO1_EN GPIO wasn't correctly set.
