[gta02-core] LCM review

Hi guys,

I've just reviewed the LCM sheet, and it looks pretty good.

I found one problem and one possible problem:
 - There was a missing connection at the base of C6007 (which I've now 
added, rev5306).
 - C6008 is missing.  This was added in GTA02, and is NC so it's 
omission might be deliberate and I've not added it.  Should we include 
this or not?

The FA2012 datasheet doesn't indicate that the filter works the same 
when driven in reverse, but unless I'm mistaken the GTA01 and GTA02 
schematics both appear to do this (U6002), although ours do not.

Because of how our components are laid out, the signals don't always go 
through the same filter component used in the gta01/gta02 schematics, 
but I think this is a sensible divergence from those schematics.

Thanks Luke!
