fix: plug memory map leak, save sp_el0, dynamic UART, kill loop
...
- Bootloader: reallocate memory map buffer when ExitBootServices fails,
so GetMemoryMap doesn't scribble past the old allocation on retry.
- vectors.S: actually store sp_el0 into the exception frame. Previously
it was read into x24 and then… vanished. EL0 tasks would wake up with
a corrupted stack pointer. Not great.
- Serial: split hardcoded 0x09000000 into a fallback default; add
SerialUpdate() so the DTB-parsed UART address actually gets used.
- DTB: add bounds check on reserved[] with PMM's 3 extra slots accounted
for, so malformed/overstuffed DTBs don't silently corrupt memory.
- PMM.h: bump kVMMaxReservedRegions 128→256, define kPMMReservedRegionCount.
- Types.h: remove `#define loop while(1)`. while(true) is fine.
- Rename IOSerial* → Serial* — the IO prefix was redundant, Serial.c
already lives under IO/.
