f586938ba2 clk: ux500: clk-sysctrl: handle clocks with no parents 
Fix clk_reg_sysctrl() to set main clock registers of new struct
clk_sysctrl even if the registered clock has no parents.

This fixes an issue where "ulpclk" was registered with all clk->reg_*
fields uninitialized, causing a -EINVAL error from clk_prepare().

5b82d03b74 clk: ux500: Add support for sysctrl clocks 
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.
