Update MBA text logs location/size in IMEM to aid tools extract
them after ramdump collection. The size of the MBA text logs is
pre-determined and limited to 4K.

We update the imem only for remoteprocs that support mba logging
otherwise the post mortem tools will show garbled data while
reading the first 4K region from MBA on unsupported SoCs.
(MBA logs are officially supported on SC7180/SC7280 SoCs only)
