tic54x: rename typedef of struct symbol_

generic gas code has a struct symbol, and tic54x typedefs a struct to symbol.
This seems at least rather confusing, and it seems like target specific headers
shouldn't  put such generic names in the global namespace preventing other
generic code from using them.

	* tic54x-dis.c (sprint_mmr): Adjust.
	* tic54x-opc.c: Likewise.
