soc/amd/picasso: Move APM_CNT_SMMINFO callsite 

Triggering SMI is not part of the semantics of global_smi_enable(), so
move it to the post_mp_init handler. Even without the !acpi_is_wakeup_s3
check we don't get PSP warnings/errors during resume, so we can drop the
workaround introduced in commit 5dbe45e0f5
in this patch.
