This looks mostly good to me (comments below) but will have as
a side effect that all clock frameworks on all platforms using PrimeCells
will need to be initialized *before* the PrimeCell devices are added.

No it doesn't - it needs the clock API to be initialized before the
first driver is probed.  As drivers are registered during the initcalls,
later than postcore level

... (to finish this) ...

drivers/amba/bus.c:postcore_initcall(amba_init);

This is the earliest that any driver can be registered, as the AMBA bus
type will not be registered until that point.  So, provided the clk API
is initialized at or before postcore level, AMBA devices are fine.

What we do need to do is add a 'busck' to amba using platforms as the
NULL connection name for the function clock in the clkdev tables will
match.
