Nathan Chancellor 0efd1fe510 scripts/dtc: Remove unused dts_version in dtc-lexer.l ...

This patch is for stable only. Commit 5a09df2087 ("scripts/dtc: Update
to upstream version v1.7.2-69-g53373d135579") upstream applied it as
part of a regular scripts/dtc sync, which may be unsuitable for older
versions of stable where the warning it fixes is present.

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.lex.c (compiled from
dtc-lexer.l):

  scripts/dtc/dtc-lexer.lex.c:641:12: warning: variable 'dts_version' set but not used [-Wunused-but-set-global]
    641 | static int dts_version = 1;
        |            ^

Remove it to clear up the warning, as it is truly unused.

Fixes: 658f29a51e ("of/flattree: Update dtc to current mainline.")
