The platform APIs are enhanced to provide support for parsing pci device
tree nodes and storing the config-space address which is later used for
pci_read/pci_write config calls.

This patch adds support for pci in xen arm. Following features are
added
a) pci device tree node is parsed and platform callback is invoked
For thunderX the callback stores the reg property, which is later
used in generating address based on the s:b:d.f
b) ABI followed is segment no is mapped to
Provide mini-os url and revision in Config.mk

Otherwise mkdir extras/mini-os fails because extras doesn't exist.

This is v2 of my mini-os splitting off patch series.
I use following runes to split off mini-os:
git filter-branch --tag-name-filter cat \
--subdirectory-filter extras/mini-os/ -- --all
# There is already a tag name 4.3.0-rc2 which points to the same commit.
git tag -d xen-4.3.0-rc2
Factor out per-subsystem build/clean/distclean-% targets, so that we can
build subsystems independently in top level directory.
The motive behind this is after splitting out mini-os from Xen tree,
stubdom is in effect a downstream of mini-os. I would like to have the
ability to build it
