clocksource: dw_apb_timer: Add common DTS glue for dw_apb_timer
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>;
+ };
