This RFC converts arch/arm to provide a common arch init for DT clock providers. Currently, the call to of_clk_init(NULL) to initialize DT clock providers is spread among several mach-dirs. Since most machs require DT clocks initialized before timers, no initcall can be used.
By adding of_clk_init(NULL) to ARM time_init(), we can remove all mach-specific .init_time hooks that basically called of_clk_init before starting timers. Some machs use the hook for more initialization, that has been moved to other hooks where required. The only exception is mach-tegra which requires clocks even earlier in .init_irq. To allow machs to call clk_of_init at any time earlier than time_init(), we first need to ensure drivers in __clk_of_table are only initialized once. The RFC is based on next-20130819 to catch up with future clock related changes. It has been tested on mach-mvebu and compile tested for all the other machs modified. All single patches have also been sent to the respective maintainers. Although some patches also modify files in mach-foo and drivers/clk, I decided to keep them in a single patch to also show what would be required for a common arch clock init.
