PERF_PMU_CAP_NO_EXCLUDE capability. This ensures that perf will
prevent us from handling events where any exclusion flags are set.
Let's also remove the now unnecessary check for exclusion flags.

For DDRC PMU, each PMU counter is fixed-purpose. There is a mismatch
between perf list and driver definition on rw_chg event.
# perf list | grep chg
hisi_sccl1_ddrc0/rnk_chg/ [Kernel PMU event]
hisi_sccl1_ddrc0/rw_chg/ [Kernel PMU event]
But the register offset of rw_chg event is not defined in the driver,
meanwhile bnk_chg register offset is mis-defined, let's fixup it.

MT bit in MPIDR_EL1 is now supported in certain HiSilicon platforms, so
the mapping between sccl_id/ccl_id and affinity level needs to be updated
from the generic encoding we originally used.

Mark noticed that the change to sibling_list changed some iteration
semantics; because previously we used group_list as list entry,
sibling events would always have an empty sibling_list.
But because we now use sibling_list for both list head and list entry,
siblings will report as having siblings.
Fix this with a custom for_each_sibling_event() iterator.

Now that all the grouping is done with RB trees, we no longer need
group_entry and can replace the whole thing with sibling_list.

This patch adds support for DDRC PMU driver in HiSilicon SoC chip, Each
DDRC has own control, counter and interrupt registers and is an separate
PMU. For each DDRC PMU, it has 8-fixed-purpose counters which have been
mapped to 8-events by hardware, it assumes that counter index is equal
to event code (0 - 7) in DDRC PMU driver. Interrupt is supported to
handle counter (32-bits) overflow.

L3 cache coherence is maintained by Hydra Home Agent (HHA) in HiSilicon
SoC. This patch adds support for HHA PMU driver, Each HHA has own
control, counter and interrupt registers and is an separate PMU. For
each HHA PMU, it has 16-programable counters and each counter is
free-running. Interrupt is supported to handle counter (48-bits)
overflow.
