drm/amd/pm: Replace one-element array with flexible-array in struct phm_clock_array
There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].
Refactor the code according to the use of a flexible-array member in
struct phm_clock_array, instead of a one-element array, and use the
struct_size() helper to calculate the size for the allocation.
