In power_supply_create_attrs(), we create static attributes as referenced
by power_supply_static_attrs[i].  After that, if we fail, we unregister
via power_supply_static_attrs[psy->properties[i]].  This is incorrect, as
psy->properties has absolutely no bearing on static attribs.  This patch
fixes it to unregister the correct attrib.

Another line which was unnecessarily line wrapped is also unwrapped.

The CAPACITY_LEVEL stuff defines various levels of charge; however, what
is the difference between them?  What differentiates between HIGH and NORMAL,
LOW and CRITICAL, etc?

As it appears that these are fairly arbitrary, we end up making such policy
decisions in the kernel (or in hardware).  This is the sort of decision that
should be made in userspace, not in the kernel.

If the hardware does not support _CAPACITY and it cannot be easily calculated,
then perhaps the driver should register a custom CAPACITY_LEVEL attribute;
however, userspace should not become accustomed to looking for such a thing,
and we should certainly not encourage drivers to provide CAPACITY_LEVEL
stubs.

The following removes support for POWER_SUPPLY_PROP_CAPACITY_LEVEL.  The
OLPC battery driver is the only driver making use of this, so it's
removed from there as well.

* Add BUG_ON(hwif->present) at the start of ide_probe_port().

* Move hwif_register() call (along with setting hwif->present) from
  ide_probe_port() to ide_device_add_all().

  As a result the port will be registered with the device tree _after_:
  - probing both devices (if both are present)
  - port reset (if hwif->reset is set)
  - restoring local IRQs state and re-enabling port IRQ

While at it:

* Rename hwif_register() to ide_register_port().

depends on BROKEN, on all other archs dma_[un]map_sg() functionality
matches with pci_[un]map_sg() one).
