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

v2: rebase and update to clk/clk-at91 branch
v3: use struct_size() and C99 trailing array
as suggested by Stephen Boyd
v4: fixed sign-off
v5: no changes
v6: no changes

I was sure I already pushed all of them to the first patch...
Fixed in v7.

We need to have clocks accessible via phandle to select them
as peripheral clock parent using assigned-clock-parents in DT.
Add support for PLLACK/PLLBCK/AUDIOPLLCK clocks where available.
Signed-off-by: Michał Mirosław <mirq-linux@rere.qmqm.pl>

v2: rebase to clk/clk-at91 branch
v3: no changes
v4: extend to whole family
v5: fix copy-and-paste bugs for SAMA5D3/4
v6: make AUDIOPLL's id separate to PLLB
