ARM: Allow SoCs to enable scatterlist chaining
Allow SoCs to enable the scatterlist chaining support, which allows scatterlist tables to be broken up into smaller allocations. As support for this feature depends on the implementation details of the users of the scatterlists, we can't enable this globally without auditing all the users, which is a very big task. Instead, let SoCs progressively switch over to using this. SoC drivers using scatterlists and SoC DMA implementations need auditing before this option can be enabled for the SoC.
