[PATCH v14 2/9] x86/resctrl: Simplify rftype flag definitions

[Babu Moger]

The rftype flags are bitmaps used for adding files under resctrl
filesystem. Some of these bitmaps have one extra level of indirection
which is not necessary.

Make them all direct definition to be consistent and easier to read.
