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: |
|
|
Define a memory region used for communication between CPU-NS and BPMP.
|
|
Typically this node is created by the bootloader as the physical address
|
|
has to be known to both CPU-NS and BPMP for correct IPC operation.
|
|
The memory region is defined using a child node under /reserved-memory.
|
|
The sub-node is named shmem@<address>.
