description:
hp300 part of the following change,
which was missed due to a sticky tag in my local tree.
pointed by Izumi Tsutsui.

> remove uvm_map_protect from cpu_startup of several ports.
> - they shouldn't be needed with the current fault handler.
> - they causes assertion failure with the recent vm_map implementation.
>
> discussed on tech-kern@.  reviewed by Chuck Silvers.
> PR/29179 from Julio M. Merino Vidal.
