[Skiboot] [PATCH v2 1/2] hdata: Use GCID in LPC setup

[Oliver O'Halloran]

The HDAT has a notion of "chip ID" which is an arbitrary numbering of
chips. This numbering isn't useful outside of the HDAT so we refer to
chips uing their Global Chip ID (GCID). Currently we're using the HDAT
chip ID in a few places and this patch fixes them.
