To pass SMMUv3 Realm Page 0 address to RMM
in Boot Manifest, BL31 needs to read SMMU_ROOT_IDR0
register. BL31 at EL3 runs in Root mode, but
CoreSight and peripherals at DEVICE0_BASE
(0x2000_0000) including SMMUv3 at 0x2B40_0000 are
mapped as MT_SECURE which results in RAZ access
to all SMMUv3 registers after enabling MMU.
This patch changes MT_SECURE mapping to EL3_PAS
resulting in MT_SECURE (ENABLE_RME = 0), and
MT_ROOT (ENABLE_RME = 1).
