The consolidation of all i.MX related base settings allows a more
global view of the settings in place.
One of the reasons for this patch is the fragmentation caused by
i.MX23 and i.MX28 SoCs using mxs-base.inc.
The changes needed to get i.MX23 and i.MX28 SoCs working have been
included in imx-base.inc file already and some values required rework
to apply to specific SoC families to avoid regressions.
