[PATCH] chipidea: Allow user to select PCI/IMX options

[Jeff Mahoney <jeffm@suse.com>]

The chipidea driver currently has needless ifneq rules in the makefile
for things that should be config options. This can be problematic,
especially in the IMX case, since the OF_DEVICE dependency will be met
on powerpc systems - which don't actually support the hardware via that
method.

This patch adds _PCI and _IMX config options to allow the user to
select whether to build the modules.
