clk: add versatile ICST307 driver The ICST307 VCO clock has a shared driver in the ARM architecture. This patch provides a wrapper into the common clock framework so we can use the implementation in the ARM architecture without duplicating the code until all ARM platforms using this VCO are moved over. At that point we can merge the driver from the ARM platform into the generic file altogether.

ARM: integrator: convert to common clock This converts the Integrator platform to use common clock and the ICST driver. Since from this point not all ARM reference platforms use the clock, we define CONFIG_PLAT_VERSATILE_CLOCK and select it for all platforms except the Integrator. Open issue: I could not use the .init_early() field of the machine descriptor to initialize the clocks, but had to move them to .init_irq(), so presumably .init_early() is so early that common clock is not up, and .init_machine() is too late since it's needed for the clockevent/clocksource initialization. Any suggestions on how to solve this is very welcome.

clk: convert ARM RealView to common clk This converts the ARM RealView machine over to using the common clock. The approach is similar to the one used for the Integrator, and we're reusing the ICST wrapper code. We have to put the clock intialization in the timer init function for the clocks to be available when initializing the timer, keeping them in early_init() is too early for the common clk. Since we now have to go down and compile drivers/clk/versatile a CONFIG_COMMON_CLK_VERSATILE symbol has been added so the proper code gets compiled into the kernel for either machine. A leftover CLK_VERSATILE in the Integrator Kconfig was fixed up to use the new symbol as well. Tested on ARM RealView PB1176.

clk: Common clocks implementation for Versatile Express This patch adds a DT and non-DT based implementation of the common clock infrastructure for Versatile Express platform. It registers (statically or using DT) all required fixed clocks, initialises motherboard's SP810 cell (that provides clocks for SP804 timers) and explicitly registers VE "osc" driver, to make the clock generators available early.
