3126c7bc41 ARM: AMBA: Add pclk definition for platforms using primecells
Add a dummy clk definition for the APB pclk signal on all platforms
using the AMBA bus infrastructure.  This ensures that these platforms
continue to work when the core amba bus code controls the APB pclk.

cd71f8f48e ARM: 5958/1: ARM: U300: fix inverted clk round rate
The clk_round_rate() functions in the U300 clocking will always
select the lowest clocking frequency due to inverted rounding
comparisons. Fix this.

0a0300dc8c ARM: Consolidate clks_register() and similar
Most machine classes want some way to register a block of clk_lookup
structures, and most do it by implementing a clks_register() type
function which walks an array, or by open-coding a loop.

Consolidate all this into clkdev_add_table().

4ebfc3dba5 [ARM] 5581/1: U300 clock updates
This adds a few default locks to the clocks (the clocks were used
before the locks were initialized by code), then renames the clocks
a bit to fit with the latest driver names (some changed during
review). Lastly it moves the initialization of the clock debugfs
entry to module_init() initcall level since the debugfs isn't up
in core_initcall().

ed31b2dfad [ARM] make U300 clk_set_rate() return a _real_ errno
Another stupid instance of "return -1"-ism.
