powerpc/pseries: Enable CMO feature during platform setup
For Cooperative Memory Overcommitment (CMO), set the FW_FEATURE_CMO
flag in powerpc_firmware_features from the rtas ibm,get-system-parameters
table prior to calling iommu_init_early_pSeries.
With this, any CMO specific functionality can be controlled by checking:
firmware_has_feature(FW_FEATURE_CMO)
