From: Austin Zheng <austin.zh...@amd.com>
[Why]
Large stack size observed in DCN4 mode support when compiling with clang.
Additional instrumentation added by compiler adds to stack size.
dml_core_mode_support ends up going over the stack size limit
due to the size of the function.
[How]
Move checks and calculations for prefetch to its own function.
