x86/resctrl: Move MSR defines into msr-index.h
msr-index.h should contain all MSRs for easier grepping for MSR numbers when dealing with unchecked MSR access warnings, for example. Move the resctrl ones. Prefix IA32_PQR_ASSOC with "MSR_" while at it. No functional changes. Signed-off-by: Borislav Petkov <bp@suse.de> Link: https://lore.kernel.org/r/20221106212923.20699-1-bp@alien8.de
