clk: scmi: Allocate CLK operations dynamically

Browse source

SCMI Clocks descriptors expose an increasing number of properties, thing
which, in turn, leads to a varying set of supported CLK operations to be
associated with each clock.

Providing statically pre-defined CLK operations structs for all the
possible combinations of allowed clock features is becoming cumbersome and
error-prone.

Allocate the per-clock operations descriptors dynamically and populate it
with the strictly needed set of operations depending on the advertised
clock properties: one descriptor is created for each distinct combination
of clock operations, so minimizing the number of clk_ops structures to the
strictly minimum needed.
