Why is this LX_GDBPARSED() instead of LX_VALUE()? From what I can tell
it doesn't need to be runtime evaluated, just assigned to something that
is macro expanded by CPP.

We should probably change the clk-provider.h header to export more
things than what it's exporting right now when COMMON_CLK is disabled.
I'm not sure why the whole thing is wrapped in a big ifdef.

Either way
