mailbox: ti-msgmgr: Move the memory region name to descriptor
For newer generation of the hardware, the naming of the region is decided at integration level and there could be additional regions as well. Hence move the region naming to be described from compatible descriptor. Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Jassi Brar <jaswinder.singh@linaro.org>
