[PATCH 03/12] debug_ll: support <asm/debug_ll.h> to get rid of mach directories

[Ahmad Fatoum]

Linux support has no arch/riscv/mach-* directories. If we can get rid of
them, we could multi-image build all images at once. Only thing holding
us back is <mach/debug_ll.h>. Add <asm/debug_ll.h> as alternative.
