d710: add support for epic4gtouch
various: compilation fixes for gcc 4.6

These changes are required to compile successfully with gcc version 4.6.

The -Wno-address option is applied to some files to bypass a warning
triggered by an rcu macro. The warning is fixed cleanly upstream, but
that fix is too risky to backport, so it is better to just silence it
this way.
