It was lately understood that the current mechanism available in the
driver to get SMU firmware info works only on internal SMU builds and
there is a separate way to get all the SMU logging counters (addressed
in the next patch). Hence remove all the smu info shown via debugfs as it
is no more useful.
Fixes: 156ec4731cb2 ("platform/x86: amd-pmc: Add AMD platform support for S2Idle")
