Subject: [PATCH 0/2] x86/resctrl: Fix Platform QoS issues for Hygon

This patch series fixes two issues regarding Platform QoS (resctrl)
support on Hygon CPUs.

The first patch adds the missing initialization sequence required for
proper resctrl functionality. The second patch corrects the bit-width
configuration for the Memory Bandwidth Monitoring (MBM) counter.
