[PATCH] firmware: arm_scmi: Fix sorting of retrieved clock rates

[Cristian Marussi]

During SCMI Clock protocol initialization, after having retrieved from the
SCMI platform all the available discrete rates for a specific clock, the
clock rates array is sorted, unfortunately using a pointer to its end as
a base instead of its start, so that sorting does not work.

Fix invocation of sort() passing as base a pointer to the start of the
retrieved clock rates array.
