Written with help from Zhenhua Huang(added the smmu node), Xin Liu(added
ufs, adsp and gpdsp nodes), Tingguo Cheng(added the rpmhpd node), Kyle
Deng(added the aoss_qmp node), Raviteja Laggyshetty(added interconnect
nodes) and Cong Zhang(added the INTID of EL2 non-secure physical timer).

The MPIDR_EL1 register value (CPU node reg) suggests they are not
part of the same cluster (as you confirmed in the psci idle domains

Are you sure about this, or is this just copypasted from sa8775p?
Thank you for your comments. I confirm with the colleague responsible
for this area, and configuring the clock this way is correct.
