Subject: [PATCH 11/42] clk: at91: clk-smd: add support for parent_hw

Add support for parent_hw in smd 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-smd were adapted
to the new API change. The switch itself for SoCs will be done
in subsequent patches.
