Should this be `default y` so that it gets enabled? Or have
config ARCH_DAVINCI_DA850 select CLK_DA850?

Otherwise, we would need to modify the defconfigs as well to
enable it.

We should also make this `depend on COMMON_CLK`. (see related comment
below.)

Did you mean CONFIG_CLK_DA850? I don't think CONFIG_CLK_DAVINCI exists.

Then we can drop this if statement.

Since there is only one platform left supported, it would probably
make more sense to make everything (including pll.o and psc.o)
`obj-$(CONFIG_CLK_DA850)` or perhaps even better, make everything
(including da8xx-cfgchip.o, pll-da850.o and psc-da850.o) `obj-y`
since the containing directory already has the conditional (and
include a comment to this effect).
