imx-vpu-hantro: fix compilation issues with -fcommon

GCC 10.2 is recently configured to include -fcommon per default, which
results in compilation error with multiple definitions of enum names.

Intoduce a patch which corrects double-defined enum names and resolves
compilation of the component.

+Subject: [PATCH] decoder_sw: resolve compilation error with -fcommon
+
+-fcommon is enabled by default in gcc10 compiler, which results in
+following build errors:
+
+decoder_sw/software/source/inc/decapicommon.h:272: multiple definition
+of `DecPicCodingType'; decoder_sw/software/linux/dwl/dwl_linux.o:
+decoder_sw/software/source/inc/decapicommon.h:272: first defined here
+
+decoder_sw/software/source/inc/dwl.h:94: multiple definition of
+`DWLInitParam'; decoder_sw/software/linux/dwl/dwl_linux.o:
+decoder_sw/software/source/inc/dwl.h:94: first defined here
+
+Drop multiple enum name definitions, which solves above compilation
+issues.
