[PATCH 0/7] DMA40 SRAM refactoring and cleanup

[Linus Walleij]

I started out by augmenting the STE DMA40 driver to get
its LCPA SRAM memory from a proper SRAM handle in the
device tree instead of as a reg cell, and then I saw
that the driver was in a bit of sad state so I did a bit
of cleanups on top.
