[ros-arm-bringup] 42175: - Remove deprecated/old/buggy/unused code. - Make MxGetNextPage return the lowest free physical page, not the highest. - This way we fragment the address space less. - Also makes calculation of "forgotten" pages when we build the PFN database earlier. - Remove MmAllocEarlyPage and use MxGetNextPage instead.
