PCI: armada8k: Fix clock resource by adding a register clock
On Armada 7K/8K we need to explicitly enable the register clock. This
clock is optional because not all the SoCs using this IP need it but at
least for Armada 7K/8K it is actually mandatory.
The binding documentation is updated accordingly.
