The AB8540 was an evolved version of the AB8500, but it was never
mass produced or put into products, only reference designs exist.
The upstream support was never completed and it is unlikely that
this will happen so drop the support for now to simplify
maintenance of the AB8500.

These clocks have been broken for a long time unfortunately, a
hurdle of misc problems made them stop working at some point
breaking USB and audio on Ux500.
The platform as such and all "regular" clocks are migrated to
OF/device tree, so let's migrate also this driver.
With this patch and the corresponding DTS fixes, and a bunch
of probe deferral fixes, audio starts working again on Ux500.

The AB8500 sysclk is just another PRCMU-controlled clock, there
is no reason why it should be in the ABx500-controlled part of
the clock implementation. Doing this and the corresponding device
tree changes makes USB work on the Ux500 again.

Clock provider drivers generally shouldn't include clk.h because
it's the consumer API. Remove the include here because this is a
provider driver. Also remove clkdev.h in files that aren't using
it.

Change soc-audio related clk_register_clkdev() device names to reflect
the ones actually used in current snd-soc-mop500 and ab8500-codec
drivers.

The patch setups the first version of the clock tree for ab850x, which
is used by u8500 platforms. Mainly sysctrl clocks are used.

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.

The abx500 clock driver is a platform driver which will be initialized
during arch init. The platform device shall be added from the ab-core
driver as a mfd child device to maintain correct boot sequence.
Depending on what ab version we use, different clock definitions will
be added.
