arm/arm64: Prepare for target-efi

v2: - Addressed all comments from Nikos and Alex - The biggest changes are * dropping the weird persistent map stuff that I never liked by taking Alex's suggestion to just create the idmap early * adding mem_region_add() to clean up memory region adding code, also improved the assignment of region fields - Also, while we found that we still have a memory map assumption (3G-4G reserved for virtual memory allocation), I only make that assumption clear. I've left removing it for an additional patch for another day. - Added psci_invoke_none() to use prior to the PSCI method being set - Added r-b's for each patch given, unless the commit changed too much - Didn't take Alex's suggestion to use x5 for stacktop when calling setup from start. I prefer explicitly loading it again. This series is a collection of patches derived from [1] that pave the way for new targets, e.g. target-efi[2]. These patches mostly address the elimination of memory map assumptions and they shouldn't have any functional changes. The last two patches are a couple of patches not related to the memory map, but they also prepare for bare metal targets. I tossed them in since I don't think they should be too controversial. This patch series is also available here [3].
