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