Earlier patches to split out the hardware init for PCIe hotplug resulted in
some one-time initializations being redone on every resume cycle. Eg.
irq/polling initialization.
This patch splits the hardware init into two parts, and separates the
one-time initializations from those so that they only ever get done once,
as intended.

Make use of the previously split out pcie_init_enable_events() function
to reinitialize the hotplug hardware on resume from suspend, but only

rpadlpar pci hotplug driver was doing some pretty bad stuff with the
sysfs files. This cleans up the logic to be sane and gets rid of the
gratuitous kset that is not needed for a simple directory like this.
Note, this patch is not even build tested, let alone run-time tested.
Someone with access to this hardware and can test would be greatly
appreciated.

We don't need a "default" ktype for a kset. We should set this
explicitly every time for each kset. This change is needed so that we
can make ksets dynamic, and cleans up one of the odd, undocumented
assumption that the kset/kobject/ktype model has.
This patch is based on a lot of help from Kay Sievers.

The PCI code in 32 and 64 bits fixes up resources differently.
32 bits uses a header quirk plus handles bridges in pcibios_fixup_bus()
while 64 bits does things in various places depending on whether you
are using OF probing, using PCI hotplug, etc...
This merges those by basically using the 32 bits approach for both,
with various tweaks to make 64 bits work with the new approach.

The previous events patch added a netlink event for every
user of the legacy /proc/acpi/event interface.
However, some users of /proc/acpi/event are really input events,
and they already report their events via the input layer.
Introduce a new interface, acpi_bus_generate_netlink_event(),
which is explicitly called by devices that want to repoprt
events via netlink. This allows the input-like events
to opt-out of generating netlink events. In summary:
events that are sent via netlink:
ac/battery/sbs
thermal
processor
thinkpad_acpi dock/bay
