PCI: Use min_align, not unrelated add_align, for size0
Commit 566f1dd52816 ("PCI: Relax bridge window tail sizing rules")
relaxed bridge window tail alignment rule for the non-optional part
(size0, no add_size/add_align). The required alignment given for
pbus_upstream_space_available(), however, was add_align which relates
only to size1 alignment.
As pbus_upstream_space_available() only selects between normal and relaxed
tail alignment of the bridge window, the different alignment only makes
relaxed tail alignment to be used more often than what was intended, which
should be harmless because relaxed tail alignment itself should work in all
cases.
For consistency, change pbus_upstream_space_available() call to use
min_align which is the alignment that is going to be used for the bridge
window in the case where size0 sized allocation is attempted.
