ARM: OMAP3: Fix smartreflex platform data regression
commit 179125085bd4ca70e8e028913193a93653bd12f7 upstream.
Commit d9d9cec02835 ("ARM: OMAP2+: Remove legacy data from hwmod for
omap3") dropped platform data that should no longer be used as we're
booting with device tree. It turns out that smartreflex is still
using platform data and produces the following errors during probe:
smartreflex smartreflex.0: invalid resource
smartreflex smartreflex.0: omap_sr_probe: ioremap fail
smartreflex: probe of smartreflex.0 failed with error -22
smartreflex smartreflex.1: invalid resource
smartreflex smartreflex.1: omap_sr_probe: ioremap fail
smartreflex: probe of smartreflex.1 failed with error -22
Let's fix the regression by adding back the smartreflex hwmod data.
The long term is to update the smartreflex driver to use device tree
based probing.

for omap3")
