[ACPI] fix HP nx8220 boot hang regression
This patch reverts the acpi_bus_find_driver() return value check
that came in via the PCI tree via 3fb02738b0
[PATCH] acpi bridge hotadd: Allow ACPI .add and .start
operations to be done independently
This particular change broke booting of some HP/Compaq laptops unless
acpi=noirq is used.

Create new interfaces to recursively add an acpi namespace object to the acpi
device list, and recursively start the namespace object. This is needed for
ACPI based hotplug of a root bridge hierarchy where the add operation must be
performed first and the start operation must be performed separately after the
hot-plugged devices have been properly configured.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
