[I/Unstable/OEM-5.13] [PATCH 03/10] platform/x86: amd-pmc: call dump registers only once

[Kai-Heng Feng]

From: Shyam Sundar S K <Shyam-sundar.S-k at amd.com>

BugLink: https://bugs.launchpad.net/bugs/1934809

Currently amd_pmc_dump_registers() routine is being called at
multiple places. The best to call it is after command submission
to SMU.
