drivers: ddr: fix unused-const-variable warnings

Depending on DDR configuration, gcc-6.x will show up unused-const-
variable messages. Use __maybe_unused specifier for all dynamic_odt
variable definitions to remove these warnings.

Memory footprint will not increase as gcc will optimize out unused
constants.
