Update Armada 8k drivers to cover newly imported DT and latest changes

Browse Source 
in simple multifunction driver.
- follow interrupt changes in DT. Split old ICU driver to function oriented
  parts and add drivers for newly defined parts (system error interrupts).
- Many drivers are children of simple multifunction driver. But after r349596
  simple MF driver doesn't longer exports memory resources, and all children
  must use syscon interface to access their registers. Adapt affected
  drivers to this fact.
