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.
