clocksource: dw_apb_timer: Add common DTS glue for dw_apb_timer

Browse Source 
Make a common device tree glue for clocksource/dw_apb_timer.
Move mach-picoxcell/time.c to be a generic device tree application
of the dw_apb_timer.

Configure mach-picoxcell to use the dw_apb_timer_of device tree
implementation in drivers/clocksource.

* Designware APB timer
Required properties:
- compatible: "snps,dw-apb-timer-sp" or "snps,dw-apb-timer-osc"
- reg: physical base address of the controller and length of memory mapped
region.
- interrupts: IRQ line for the timer.
- clock-frequency: The frequency in HZ of the timer.
- clock-freq: For backwards compatibility with picoxcell
Example:
timer1: timer@ffc09000 {
compatible = "snps,dw-apb-timer-sp";
interrupts = <0 168 4>;
clock-frequency = <200000000>;
reg = <0xffc09000 0x1000>;
};
timer2: timer@ffd00000 {
compatible = "snps,dw-apb-timer-osc";
interrupts = <0 169 4>;
clock-frequency = <200000000>;
reg = <0xffd00000 0x1000>;
};
