Subject: [PATCH 05/42] clk: at91: clk-pll: add support for parent_hw
Add support for parent_hw in pll clock driver. 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-pll were adapted
to the new API change. The switch itself for SoCs will be done
in subsequent patches.
