dts: Rename DW APB timer compatible strings 

"dw-apb-timer-osc" and "dw-apb-timer-sp" are the same implementation of the
DW APB timer, just fed by different clocks. Thus, deprecate both
"dw-apb-timer-osc" and "dw-apb-timer-sp" in lieu of "dw-apb-timer".

v3:
- Split out a separate that cleans up the timer entries and clock information.
- Clearly states which binding is deprecated in the bindings doc.

v2:
- Deprecate the "dw-apb-timer-osc" and "dw-apb-timer-sp" but maintain
  backwards compatibility in the driver.

* Designware APB timer
Required properties:
- compatible: "snps,dw-apb-timer-sp" or "snps,dw-apb-timer-osc"
- compatible: One of:
"snps,dw-apb-timer"
"snps,dw-apb-timer-sp" <DEPRECATED>
"snps,dw-apb-timer-osc" <DEPRECATED>
- reg: physical base address of the controller and length of memory mapped
region.
- interrupts: IRQ line for the timer.
