As reported by Rob Herring[1] there were some mismatched types between
drivers/clk/ux500/clk.h and the corresponding function definitions:

drivers/clk/ux500/clk-prcc.c:145:13: error: conflicting types for 'clk_reg_prcc_pclk'
drivers/clk/ux500/clk-prcc.c:155:13: error: conflicting types for 'clk_reg_prcc_kclk'

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

The abx500 sysctrl clocks are using the ab8500 sysctrl driver to
modify the clock hardware. Sysctrl clocks are represented by a
ab8500 sysctrl register and with a corresponding bitmask.

The sysctrl clocks are slow path clocks, which means clk_prepare
and clk_unprepare will be used to gate|ungate these clocks.

In clk_reg_prcmu(), clk->hw.init field is assigned with a
reference local to clk_reg_prcmu() function.

This patch replaces references to clk->hw.init with calls
to __clk_get_name when called after clock registration.

This patch applies on top of v3.9-rc4.

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.

This fixes a bit error in the U8500 clock implementation: the
unused p2_pclk12 registered at bit 12 in periphereral group 6
was defined as using bit 11 rather than bit 12.

When walking over and disabling the unused clocks in the tree
at late init time, p2_pclk12 was disabled, by effectively
clearing the but for p2_pclk11 instead of bit 12 as it should
have, thus disabling gpio block 6 and 7.

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.
