[PATCH] docs: fix pointers to io-mapping.rst and io_ordering.rst files

[Mauro Carvalho Chehab <mchehab+huawei@kernel.org>]

Those files got moved, but cross-references still point to the
wrong places.

Fixes: fcd680727157 ("Documentation: Add io-mapping.rst to driver-api manual")
Fixes: d1ce350015d8 ("Documentation: Add io_ordering.rst to driver-api manual")
Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
