[RFC PATCH v2 09/11] x86/resctrl: Accept asymmetric RDT allocation features

[Tony Luck]

Some systems expose asymmetric allocation features without setting the
X86_FEATURE_RDT_A bit for symmetric allocation.

Allow resctrl to probe allocation resources when either the symmetric or
asymmetric allocation feature is enabled.
