Krzysztof Kozlowski 0121898ec0 dt-bindings: Correct indentation and style in DTS example
DTS example in the bindings should be indented with 2- or 4-spaces and
aligned with opening '- |', so correct any differences like 3-spaces or
mixtures 2- and 4-spaces in one binding.

No functional changes here, but saves some comments during reviews of
new patches built on existing code.

description: |
Arm Trace Buffer Extension (TRBE) is a per CPU component
for storing trace generated on the CPU to memory. It is
accessed via CPU system registers. The software can verify
if it is permitted to use the component by checking the
TRBIDR register.

Exactly 1 PPI must be listed. For heterogeneous systems where
TRBE is only supported on a subset of the CPUs, please consult
the arm,gic-v3 binding for details on describing a PPI partition.
