ppc.tmpl: clarify comments, fix yaboot.conf for Apple systems

Browse Source 
So there's actually two copies of yaboot on a PPC image, and they each
use different config files:

  ppc/chrp/yaboot --> /etc/yaboot.conf
  ppc/mac/yaboot  --> /ppc/ppc{32,64}/yaboot.conf

So we need two copies of yaboot.conf - one in each place - to
boot properly (or all three if we're making hybrid images). Whee!

The comments should now make this more clear for future reference.

## NOTE: there's two different bootloader setups here:
## ppc/chrp: for normal PPC systems. needs 'addnote' run on yaboot.
## uses /etc/yaboot.conf, as is the default.
## ppc/mac: for PowerMacs. no 'addnote' (it breaks some Macs!)
## ofboot.b picks one of /ppc/ppc{32,64}/yaboot.conf for yaboot,
