[PATCH 2/3] arm64: dts: amlogic: Fix the register name of the 'DBI' region

DT 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 DT for both Meson platforms.
