Please, keep them sorted.

While this change is almost (*) okay per se, I think we can address more
while at it.
- Make the header inclusions ordered (also fix the location of clk.h)
- drop other proxy (device.h) or unneeded headers (bitops.h as it's implied by bitmap.h)
- add missing ones (dev_printk.h, device/devres.h, ...)

(*) no, kernel.h provides more for this driver, for example, your patch
misses types.h.
