[PATCH v6 21/42] x86/resctrl: Move mba_mbps_default_event init to filesystem code

[James Morse]

mba_mbps_default_event is initialised base on whether mbm_local or
mbm_total is supported. In the case of both, it is initialised to
mbm_local. mba_mbps_default_event is initialised in core.c's
get_rdt_mon_resources(), while all the readers are in rdtgroup.c.

After this code is split into architecture specific and filesystem code,
get_rdt_mon_resources() remains part of the architecture code, which
would mean mba_mbps_default_event has to be exposed by the filesystem
code.

Move the initialisation to the filesystem's resctrl_mon_resource_init()
