6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: ZhenGuo Yin <zhenguo.yin@xxxxxxx>
[ Upstream commit 9f05cfc78c6880e06940ea78fbc43f6392710f17 ]
Register RLC_SPM_MC_CNTL is not blocked by L1 policy, VF can
directly access it through MMIO during SRIOV runtime.
v2: use SOC15 interface to access registers
