Add the device-tree nodes for the TBUs (translation buffer units) that
are present on the sdm845 platforms. The TBUs can be used debug the
kernel and provide additional information when a context faults occur.

Describe the all registers, clocks, interconnects and power-domain
resources that are needed for each of the TBUs.
