From: Dinh Nguyen <dinguyen@xxxxxxxxxx>
"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 bindingd doc.
v2:
- Deprecate the "dw-apb-timer-osc" and "dw-apb-timer-sp" but maintain
backwards compatibility in the driver.
