[RFC PATCH v2 16/19] arm_mpam: resctrl: Report counter assignment per resource

[Jinjie Ruan]

resctrl_arch_mbm_cntr_assign_enabled() says assignment is on by checking
whether the resource is the L3. A platform whose L3 has no bandwidth
counters is then told assignment is on, although no counters were set
up.

Report the per-resource flag MPAM sets when it sets up the assignable
counters. Other resources can then report their own state.
