dt-bindings: PCI: amlogic: Fix the register name of the DBI region 



Binding incorrectly specifies the 'DBI' region as 'ELBI'. DBI is a must
have region for DWC controllers as it has the Root Port and controller
specific registers, while ELBI has optional registers.

Hence, fix the binding. Though this is an ABI break, this change is needed
to accurately describe the PCI memory map.
