platform/x86/amd/pmf: change amd_pmf_init_features() call sequence

To sideload pmf policy binaries, the Smart PC Solution Builder provides a
debugfs file called "update_policy"; that gets created under a new debugfs
directory called "pb" and this new directory has to be associated with
existing parent directory for PMF driver called "amd_pmf".

In the current code structure, amd_pmf_dbgfs_register() is called after
amd_pmf_init_features(). This will not help when the Smart PC builder
feature has to be assoicated to the parent directory.

Hence change the order of amd_pmf_dbgfs_register() and call it before
amd_pmf_init_features() so that when the Smart PC init happens, it has the
parent debugfs directory to get itself hooked.
