Relax the object locking assertion in vm_page_lookup().  Now that a radix
tree is used to maintain the object's collection of resident pages,
vm_page_lookup() no longer needs an exclusive lock.

o  Retrive the part number (CP2103 etc) from the hardware on attach.
o  The CP2101 and CP2102 do not support GPIO pin use at all, enforce this.
o  Support reading the GPIO status on the second port of the CP2105.  More
   work is needed before the CP2105 GPIO pins can be used as outputs.

We really need to get the bsd.own.mk from this tree so the
correct options are set.
Also defined NO_PWD_OVERRIDE to match behavior of fmake.
Use readlocking now that assertions on vm_page_lookup() are relaxed.

Per the comment, we cannot rely on bsd.own.mk
we could be on an old system that knows noting of MK_BMAKE
or on an almost up to date one that is defaulting it to "no"
neither of which will work.
Set errno to ETIMEDOUT if an SCTP association times out during
setup.
