dt-bindings: display/ti: Add optional property to set memory bandwidth limit
max-memory-bandwidth can be used to specify the maximum bandwidth dispc
can use when reading display data from main memory.
In some SoC (am437x for example) we have memory bandwidth limitation
which causes underflow in the display subsystem.
