Declare a ramoops memory segment to aid debugging for those without UART access. Verified to carry console log when holding volume down for 15 seconds.
I was unable to find any ramoops-like memory region used in the 8916 downstream kernels, so the picked region is the last MB in System RAM. No memory region for ramoops-like support was found downstrea, so the arbitrarily picked region is the last MB of System RAM.
