Hmm. That sounds like a separate patch. Cleanup isn't the same as adding
new DT compatible values...

It's slightly unclear whether "snps,dw-apb-timer-sp" is deprecated.
Also, listing the non-deprecated values first would be a good hint to
people which they should use. How about:

compatible: One of:
	"snps,dw-apb-timer"
	"snps,dw-apb-timer-sp" <DEPRECATED>
	"snps,dw-apb-timer-osc" <DEPRECATED>
