By itself this does nothing. You can't set this symbol to 'y', even if
ARCH_STI is 'y', right? Of course, ARCH_STI will select this symbol (see
11/12) otherwise it would be inert. But as ARCH_STI selects
CLKSRC_ST_LPC I'd say this dependency isn't actually needed.

Are other selects of CLKSRC_ST_LPC expected to be added in the future?
If not, CLKSRC_ST_LPC should operate in lockstep with ARCH_STI. In that
case you might as well not bother with CLKSRC_ST_LPC and use ARCH_STI
directly. (But that forces you to move the select statement below into
the ARCH_STI entry, which might be ugly.)
