I guess this is more of a representative dependency, but you're right,
the likelihood is that no one is likely to accidentally enable it.

I can remove it.

Although true, there might be cases where we need to stop this from
being enabled on all ARCH_STI platforms. It'll be easier to move
CLKSRC_ST_LPC around in arch code than to start renaming this symbol.

I'd prefer to keep this as CLKSRC_ST_LPC if you're not passionate
about the alternative.

I believe the new line comes in the next patch.
