[arty] 29928: Fix memory map to kernel mode. Allow prep serial in kdcom (and stop clobbering the data miss handler). Clean up boot mapping a bit. Silence some boot time spam. Enable not present page handler (yes, this routing actually works). Scan physical memory on the (virtually 100%) chance that open firmware will somehow have a buggy implementation of the memory object, or we're on prep hardware. Initialize syscall trap early, so we can do DbgPrint.

Log:
Fix memory map to kernel mode.
Allow prep serial in kdcom (and stop clobbering the data miss handler).
Clean up boot mapping a bit.
Silence some boot time spam.
Enable not present page handler (yes, this routing actually works).
Scan physical memory on the (virtually 100%) chance that open firmware will
somehow have a buggy implementation of the memory object, or we're on prep
hardware.
Initialize syscall trap early, so we can do DbgPrint.
