dtc: Remove unused dts_version in dtc-lexer.l 

A recent strengthening of -Wunused-but-set-variable (enabled with -Wall)
in clang under a new subwarning, -Wunused-but-set-global, points out an
unused static global variable in dtc-lexer.l:

  ../dtc-lexer.l:42:12: error: variable 'dts_version' set but not used [-Werror,-Wunused-but-set-global]
     42 | static int dts_version = 1;
        |            ^

This variable has been unused since commit 4e1a0a0 ("Remove support for
the legacy DTS source file format."). Remove it to clear up the warning.
