On dra7 we're missing the smartreflex and hdq nodes with their
related "ti,hwmods" property that the SoC interconnect code needs.
Note that this will only show up as a bug with "doesn't have
mpu register target base" boot errors when the legacy platform
data is removed.
Note that the related driver also needs to be updated to probe
using device tree and get the platform data passed to it using
auxdata with arch/arm/mach-omap2/pdata-quirks.c.
Let's also update the related binding documentation while at it.

Have you checked TRM for these?
http://www.ti.com/lit/ug/sprui30d/sprui30d.pdf
These are disabled on the SoC and marked as reserved.
Then why do we still have legacy hwmod data for them?
We should probably drop them - probably legacy of autogeneration at
some point in history.
