clk: at91: clk-system: add support for parent_hw
Add support for parent_hw in system clock drivers.
With this parent-child relation is described with pointers rather
than strings making registration a bit faster.
All the SoC based drivers that rely on clk-system were adapted
to the new API change. The switch itself for SoCs will be done
in subsequent patches.
