Add mux table option. This is necessary for IP versions that has
gaps in the range of available clock sources (e.g. SAMA7G5).

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.

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

Lockdep warns about a possible circular locking dependency because using
syscon_node_to_regmap() will make the created regmap get and enable the
first clock it can parse from the device tree. This clock is not needed to
access the registers and should not be enabled at that time.
Use the recently introduced device_node_to_regmap to solve that as it looks
up the regmap in the same list but doesn't care about the clocks.

It's just some static data that doesn't get changed after being used.
Mark it const everywhere.
