thorpej c98f5f31c8 Fix a problem reported by jmcneill@ where by a system with multuple i2c 
busses would end up with "ghost" device instances on the second bus.  This
issue was previously masked on ARM systems by the empty-child-devices
array issue fixed recently (that effectively blocked all indirect config
of i2c busses on those systems).

To fix this problem, we require that indirectly-configured devices have
to fully specify their parent spec and address, e.g.:

foo* at iic0 addr 0x55

NOT

foo* at iic? addr ?

or even:

foo* at iic? addr 0x55

This is needed because of how indirect configuration works... attach
directives in the kernel config file are enumerated, calling the bus's
search routine, which in the case of i2c, enumerates all i2c addresses
and calls the match routine for each address.  Because we can't always
reliably probe for i2c devices, we ended up with erroneous matches.

Direct configuration of i2c is still allowed to use wildcarded parent specs
and locators.
