Simplify the build file as
- dtc_gen creates an unnecessarily broad (and confusing) dependency list
by using glob([".h"]) as its header list. Instead, dtc now lists
explicitly the few headers it actually needs;
- generating dtc-lexer.lex.c does not require dtc-parser.{c,h};
- Bison can be told to directly create dtc-parser.{c,h} so no need for
an unnecessarily broad copying of *.[ch] to move some intermediate
results.
As a result, we get two genrule() wrapping the source files respectively
generated through lex and bison, which can be listed as srcs of dtc.
Test: bazel build //:all
