Make sure that we use the pci_rescan_remove_lock when we remove
or add functions from/to the bus.

Inline get_zdev to save ~200 bytes of kernel text for CONFIG_PCI=y.
Also rename the function to to_zpci to make clear that we don't do
reference counting here.

Add a bunch of s390 specific pci attributes to help
identifying pci functions.

Let the driver core handle attribute creation by putting all s390
specific pci attributes in an attribute group which is referenced
by pdev->dev.groups in pcibios_add_device.

Introduce the zpci_attr macro to create read only sysfs attributes
to avoid duplicate code.

driver-core now supports synchrnous self-deletion of attributes and
the asynchrnous removal mechanism is scheduled for removal. Use it
instead of device_schedule_callback().
* Conversions in arch/s390/pci/pci_sysfs.c and
drivers/s390/block/dcssblk.c are straightforward.
* drivers/s390/cio/ccwgroup.c is a bit more tricky because
ccwgroup_notifier() was (ab)using device_schedule_callback() to
purely obtain a process context to kick off ungroup operation which
may block from a notifier callback.
Rename ccwgroup_ungroup_callback() to ccwgroup_ungroup() and make it
take ccwgroup_device * instead. The new function is now called
directly from ccwgroup_ungroup_store().
ccwgroup_notifier() chain is updated to explicitly bounce through
ccwgroup_device->ungroup_work. This also removes possible failure
from memory pressure.
Only compile-tested.

Add some s390 specific sysfs attributes to the PCI device directory.
The following attributes are introduced:
- function_id (PCI function ID)
- function_handle (PCI function handle)
- pchid (PCI channel ID)
- pfgid (PCI function group ID aka PCI root complex)
