drivers: ddr: fsl: 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. Signed-off-by: Thomas Schaefer <thomas.schaefer@kontron.com> Signed-off-by: York Sun <york.sun@nxp.com>
