This series extends AT91 with clock references to PCKx and PLLA/AUDIOPLL.

First patch simplifies clock table allocation. Next two update the table
with missing clock pointers and IDs.

Michał Mirosław (3):
  clk: at91: optimize pmc data allocation
  clk: at91: allow setting PCKx parent via DT
  clk: at91: sama5d2: allow setting all PMC clock parents via DT

Alloc whole data structure in one block. This makes the code shorter,
more efficient and easier to extend in following patch.

This exposes PROGx clocks for use in assigned-clocks DeviceTree property
for selecting PCKx parent clock.

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.
