  x86/resctrl: Make resctrl_arch_rmid_read() return values in bytes (2022-09-23 14:25:05 +0200)

----------------------------------------------------------------
- More work by James Morse to disentangle the resctrl filesystem generic
code from the architectural one with the endgoal of plugging ARM's MPAM
implementation into it too so that the user interface remains the same

- Properly restore the MSR_MISC_FEATURE_CONTROL value instead of blindly
overwriting it to 0
