Actual slot table PHB1 devices are below:

habanero/slottable: Remove Network Mezz(2, 0) from PHB1.
3d0e3d8 
With addition of latest callback of check_all_slot_table found below
error message in habanero platform.

[   17.069198739,3] PCI: built-in device not found: Network Mezz (loc: 10)
open-power#54

So PHB1 already having one Network Mezz(1,0) which is the only one there in the
habanero platform design layout. check_all_slot_table found the additional
Network Mezz(2,0) in slot table is in-correct. Fix this by removing it.
