Simplify devm_ioport_unmap() implementation by dedicated API
devres_release(), compared with current solution, namely
ioport_unmap() + devres_destroy(), devres_release() has below advantages:

- it is simpler if devm_ioport_unmap()'s parameter @addr was ever
  returned by devm_ioport_map().

- it can avoid unnecessary ioport_unmap(@addr) if @addr was not
  ever returned by devm_ioport_map().

devres_release() has the following advantages:

Patch series "devres: A couple of cleanups".

A couple of ad-hoc cleanups. No functional changes intended. 


This patch (of 2):

The devm_*() APIs are supposed to be called during the ->probe() stage. 
Many drivers (especially new ones) have switched to use dev_err_probe()
for error messaging for the sake of unification.  Let's do the same in the
devres APIs.

The pcim_*() functions in lib/devres.c are guarded by an #ifdef CONFIG_PCI
and, thus, don't belong to this file. They are only ever used for PCI and
are not generic infrastructure.

Move all pcim_*() functions in lib/devres.c to drivers/pci/devres.c.
Adjust the Makefile.

Add drivers/pci/devres.c to Documentation.

The other error prints in this call show the resource which wsan't valid,
so add this to the first print when it checks for basic validity of the
resource.

Add devm_arch_io_reserve_memtype_wc() as managed wrapper around
arch_io_reserve_memtype_wc(). Useful for several graphics drivers
that set framebuffer memory to write combining.
