Log:
Fix a build error when using bison-2.4

This fixes one of the errors from using bison-2.4, but there are more.

This one in details is the following error:

  BISON   build/util/dtc/dtc-parser.tab.c
  HOSTCC  build/util/dtc/dtc-parser.tab.o
/home/leio/dev/coreboot-v3/util/dtc/dtc-parser.y: In function ?\226?\128?\152yyuserAction?\226?\128?\153:
/home/leio/dev/coreboot-v3/util/dtc/dtc-parser.y:154: error: expected ?\226?\128?\152;?\226?\128?\153 before ?\226?\128?\152}?\226?\128?\153 token
make: *** [/home/leio/dev/coreboot-v3/build/util/dtc/dtc-parser.tab.o] Error 1

Note that 2.4.1 might be made to still work without the semi-colon for some languages, but I
understand 2.5 then still won't work without one. As it builds fine with this change with
bison-2.3, it should be safe to just add the semicolon.

The remaining error is the following:

/home/leio/dev/coreboot-v3/util/dtc/dtc-lexer.l: In function ?\226?\128?\152yylex?\226?\128?\153:
/home/leio/dev/coreboot-v3/util/dtc/dtc-lexer.l:73: error: ?\226?\128?\152yylval?\226?\128?\153 undeclared (first use in this function)
/home/leio/dev/coreboot-v3/util/dtc/dtc-lexer.l:73: error: (Each undeclared identifier is reported only once
/home/leio/dev/coreboot-v3/util/dtc/dtc-lexer.l:73: error: for each function it appears in.)

dtc-parser.tab.h doesn't seem to get an "extern YYSTYPE yylval" declaration, which per documentation should
only happen for pure parser cases ("%define api.pure"), but I can't find any such declaration in dtc to cause
the problem.

Note that upstream dtc builds fine with bison-2.4
