omap_hsmmc_init and omap_mux related functions as __init) changed DSI

"Here's one more kernel panic fix that I dropped from last weeks

This is a fix for the regression caused by fixing an earlier
regression for smsc911x fixed regulators :(
Turns out that we have more than one smsc911x on some boards,
and the earlier fix causes a kernel panic for board trying to
register second smsc911x instance, even if the second smsc911x
is on an add-on board that is not connected.
Note that the boards with second smsc911x will also need to be

The OMAP McBSP driver stack used to contain two different

the IP, while the other driver was the ASoC DAI driver.
There were global, shared structures, in different places,
the McBSP instances are reffered with id numbers (sometimes
0 based, in other cases 1 based id numbers).
Create one single driver for OMAP McBSP with name: omap-mcbsp.
Convert the old omap-mcbsp driver initially to be a library

When using the SMPS regulators to scale voltages, the regulator
framework may pass a minimum voltage that is not an exact OPP voltage.
For the VC/VP controlled voltage domains, we must ensure that the
voltage requested is the exact voltage from the OPP table. This is
especially critical when using SR.
To fix, voltdm_scale() uses the target voltage passed to walk through
the OPP voltages until it finds a voltage that is >= one of the OPP
voltages.
