clk: keystone: Fix discarded const qualifiers

Add const qualifiers to the pointers returned from 'container_of' macro
to prevent breaking the const promise on const struct pointers from
parameters.

Once you have a mutable container structure pointer, you can change
structure fields through it, which violates the const guarantee.
