The interrupt map wasn't being allocated properly, preventing IRQs from being
allocated to children of the PCIe bus. Fix this by cloning the ofw_pcib_pci
code, which handles all cases -- device tree and probed.
In the future this may become a subclass of the ofw_pcib_pci driver, but as
that's not an exported class, it's cloned for now.

Summary:
ofw_parse_bootargs() was added in r306065 as an attempt to unify the

loader.conf for uboot have this in the list, but the default one

The PT_DETACH case above the sendsig: label already looped over all
threads clearing flags in td_dbgflags. Reuse this loop to clear
TDB_SUSPEND and move the logic out of the sendsig: block.
Most of the conditionals in the 'sendsig:' block are now only different
for PT_ATTACH vs other continue requests. Pull the PT_ATTACH-specific
logic up into the PT_ATTACH case and simplify the 'sendsig:' block. This
also permits moving the unlock of proctree_lock above the sendsig: label
since PT_KILL doesn't hold the lock and and the other cases all fall
through to the label.

loader.conf is also different between machines. On arm it's a minimal
one that's not quite compatible with the default one. On arm it's
minimal for speed, which is good, but there's also extra things in it
relative to the default on which break loading FDT which is bad. This
doesn't address that issue, but instead ensures the minimal one for
arm is used.
A similar issue for mips exists, but since we can have a beri variant
of /boot/loader and a uboot variant, I'm leaving that mess alone for
the moment.

This fixes a panic when attaching to an already-stopped process after
r325028. While here, clean up a few other things in the control flow
of the 'sendsig' section:
- Only check for P_STOPPED_TRACE rather than either of P_STOPPED_SIG
or P_STOPPED_TRACE for most ptrace requests. The signal handling
code in kern_sig.c never sets just P_STOPPED_SIG for a traced
process, so if P_STOPPED_SIG is stopped, P_STOPPED_TRACE should be
set anyway. Remove a related debug printf. Assuming P_STOPPED_TRACE
permits simplifications in the 'sendsig:' block.
- Move the block to clear the pending thread state up into a new
block conditional on P_STOPPED_TRACE and handle delivering pending
signals to the reporting thread and clearing the reporting thread's
state in this block.
- Consolidate case to send a signal to the process in a single case
for PT_ATTACH. The only case that could have been in the else before
was a PT_ATTACH where P_STOPPED_SIG was not set, so both instances
of kern_psignal() collapse down to just PT_ATTACH.

Add notes to each of these that specifically state that results are
undefined if the strings overlap. In the case of memcpy, we document
the overlapping behavior on FreeBSD (pre-existing). For str*, it is
left unspecified, however, since the default (and x86) implementations
do not handle overlapping strings properly.

r325681 fixed a NULL pointer dereference on RPi3 caused by a lack of
functionality in uboot's EFI implementation. That rev checked the boot1
load path for NULL but not the load device. In practice if the former
works the latter will as well, but improve correctness by checking each
separately.

There were two things wrong. First, the wrong path was listed in .PATH
statement. Second, BOOTSRC wasn't yet defined for the .PATH, so it
didn't properly add it. Third, even if these were right, . was in the
path before, so it wouldn't have worked. Replace this with a simple
loop so the proper loader.rc gets selected.

In capability world this is also annoying because we getting error that
