Before deferring the assignment of memstart_addr in a subsequent patch, to the moment where all memory has been discovered and possibly clipped based on the size of the linear region and the presence of a mem= command line parameter, we need to ensure that memstart_addr is not used to perform __va translations before it is assigned. One such use is in the generic early DT discovery of the initrd location, which is recorded as a virtual address in the globals initrd_start and initrd_end. So wire up the generic support to declare the initrd addresses, and implement it without __va() translations, and perform the translation after memstart_addr has been assigned.
