ARM: dts: msm: modify memory reservation requirements for tmc-etr on 9625



The CoreSight TMC-ETR driver now meets its coherent memory allocation
requirement using dma_alloc_coherent api instead of custom
allocate_contiguous_ebi function. Add support to the device tree to
specify this memory requirement.

Also retain the dt entry to allocate contiguous memory via
allocate_contiguous_ebi api until the corresponding driver changes go
in to prevent breaking TMC-ETR functionality.
