[PATCH v5 07/29] x86,fs/resctrl: Rename some L3 specific functions

[Tony Luck <tony.luck@intel.com>]

All monitor events used to be connected to the L3 resource so
it was OK for function names to be generic. But this will cause
confusion with additional events tied to other resources.

Rename functions that are only used for L3 features:

arch_mon_domain_online()	-> arch_l3_mon_domain_online()
mon_domain_free()		-> l3_mon_domain_free()
domain_setup_mon_state()	-> domain_setup_l3_mon_state

No functional change.
