outer_disable() is defined to safely turn the L2 cache off without data
loss: this means that outer_flush_all() should never be called unless
you need to implement some special L2 cache disabling, and even then
only from your replacement L2 cache disable function.

This will delete some redundant calling of sirfsoc_of_pwrc_init() and
sirfsoc_memc_init() for non-CSR platforms if we use multi-platform.

Pull ARM SoC non-cricitical bug fixes from Arnd Bergmann:
"These are various bug fixes that were not considered important enough
for merging into 3.10.
The majority of the ARM fixes are for the OMAP and at91 platforms, and
there is another set of bug fixes for device drivers that resolve
'randconfig' build errors and that the subsystem maintainers either
did not pick up or preferred to get merged through the arm-soc tree."

In prima2, some functions of checking DT is registered in initcall
level. If it doesn't match the compatible name of sirf, kernel
will panic. It blocks the usage of multiplatform on other verndor.
The error message is in below.

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,
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.
