The SSI protocol implementation has an incorrect dependency on the OMAP_SSI
driver, which allows SSI to be built-in while the underlying OMAP_SSI
implementation is a loadable module, causing a link error.
This changes the dependency to the simpler 'depends on OMAP_SSI' that also
ensures that SSI-protocol can only be a module if OMAP_SSI is not built-in.

The Nokia N900's modem is connected via Synchronous Serial Interface (SSI),
which is a legacy version of MIPI's High-speed Synchronous Serial Interface
(HSI).
The handles the GPIOs for enabling and resetting the modem and instanciates
ssi-protocol for data exchange. It does not yet support exchanging voice data
with the modem.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.
