Subject[PATCH v3 3/3] clk: at91: sama5d2: allow setting all PMC clock parents via DT
We need to have clocks accessible via phandle to select them
as peripheral clock parent using assigned-clock-parents in DT.
PLLACK and AUDIOPLLCK were missing for sama5d2. Add them.

v2: rebase to clk/clk-at91 branch
