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.
MFC after: 3 weeks
The cp110 clock controller controls the clocks and gate of the CP110
hardware block.
Every clock/gate are implemented except the NAND clock.
