hexagon architecture system emulation: part 2/3

This series includes the k0 and TLB locking implementation.  This was briefly
discussed on-list at https://lists.nongnu.org/archive/html/qemu-devel/2024-01/msg04801.html
and perhaps we can continue/follow-up discussion on the relevant patch(es)
in this series.
