Actions Semi ARM64 DT for v5.10:

Browse Source 
- Fix the memory region used by pinctrl and sps drivers on the S700 SoC.
   The issue is fixed by limiting the address space used by pinctrl driver.
   In hardware these two are separate subsystems but the hw engineers somehow
   merged the registers space into one. So we now limit the address space with
   appropriate offsets for the two drivers.
 
 - Add DMA controller support for S700 SoC. The relevant driver changes are
   picked up by DMA Engine mainatainer. The DMA on this SoC can be used for
   mem-to-mem and mem-to-peripheral transfers.
