Some code manually calls local_bh_disable() and spin_lock() but
then calls spin_unlock_bh() (or vice versa).
Our code then calls local_bh_disable() again from spin_lock()
which means we have the thread pin count increased twice and that
means we get out of synch and are still pinned when returning to
user space.
Avoid this by adding the explicit local_bh_{enable,disable}() to
the spin_[un]lock_bh() versions.

Restructure some code and add support for various "managed" versions
for PCI resource management.
This is beyond of what iwlwifi needs but some was found with other
wireless drivers and it mostly all goes together.
Add one FreeBSD sepcific feature returning the resource rather than

Add dummy functions for dealing with "HotPlug" events which we currently
do not support.
Add pci_dev_get(), pci_find_ext_capability() and pci_pme_capable().
The added pcie_find_root_port() is a bit special as we need to create
another linux pci device; for that make lkpinew_pci_dev() public
which is also helpful for other cases when we want to use the Linux
routines to check for device identifiers only and need a container
for the "bsddev" to use natively. This has proven to avoid basic
checking code for the sake of rewriting it to native field names
elsewhere. Given we cache the newly created "root" we also need to
make sure we clean it up.

Given all the code does operate on struct ifnet, the last step in this
longer series of changes now is to rename struct net_device to
struct ifnet (that is what it was defined to in the LinuxKPi code).
While mlx4 and OFED are "shared" code the decision was made years ago
to not write it based on the netdevice KPI but the native ifnet KPI
for most of it. This commit simply spells this out and with that
frees "struct netdevice" to be re-done on LinuxKPI to become a more
native/mixed implementation over time as needed by, e.g., wireless
drivers.

armv6 and armv7 systems already were 1000Hz. The other armv5 were a
mix of 100 and 1000. This changes them to 1000. Should there be
issues, we can add options HZ=100 to the systems that have bad
performance at the drop of a hat.
mips is a lot more complicated. But most of the systems are already
1000HZ. The hardware exceptions are all fast enough to run at
1000Hz. MALTA is our primary emulator, and history has shown emulators
tend to like 100Hz better, so run those systems at 100Hz. As with arm,
any system that shows a huge performance regression can reverted to
100Hz easily.
This was going to be committed well in advance of the 13 branch, but
it was delayed and forgotten til now.
