Subject: [PATCH v13 03/10] x86/resctrl: Rename rftype flags for consistency
resctrl associates rftype flags with its files so that files can be chosen
based on the resource, whether it is info or base, and if it is control
or monitor type file. These flags use the RF_ as well as RFTYPE_ prefixes.
Change the prefix to RFTYPE_ for all these flags to be consistent.

v13: Changes related to rebase. New file "sparse_masks" flag has been updated.
v12: Moved the RFTYPE_MON_BASE definition to patch 10. (Boris)
