The RMM (Realm Management Monitor) provides functionality that can be
accessed by SMC calls from the host.
The SMC definitions are based on DEN0137[1] version 2.0-bet0

Changes since v12:
* Updated to RMM spec v2.0-bet0
Changes since v9:
* Corrected size of 'ripas_value' in struct rec_exit. The spec states
this is an 8-bit type with padding afterwards (rather than a u64).
Changes since v8:
* Added RMI_PERMITTED_GICV3_HCR_BITS to define which bits the RMM
permits to be modified.
Changes since v6:
* Renamed REC_ENTER_xxx defines to include 'FLAG' to make it obvious
these are flag values.
Changes since v5:
* Sorted the SMC #defines by value.
* Renamed SMI_RxI_CALL to SMI_RMI_CALL since the macro is only used for
RMI calls.
* Renamed REC_GIC_NUM_LRS to REC_MAX_GIC_NUM_LRS since the actual
number of available list registers could be lower.
* Provided a define for the reserved fields of FeatureRegister0.
* Fix inconsistent names for padding fields.
Changes since v4:
* Update to point to final released RMM spec.
* Minor rearrangements.
Changes since v3:
* Update to match RMM spec v1.0-rel0-rc1.
Changes since v2:
* Fix specification link.
* Rename rec_entry->rec_enter to match spec.
* Fix size of pmu_ovf_status to match spec.
