drm/i915: Fix declaration of intel_gmbus_{is_forced_bit/is_port_falid}

Description:
intel_gmbus_is_forced_bit is no extern as its body is right below.
Likewise for intel_gmbus_is_port_valid.

This fixes a compilation issue with clang. An initial version of this patch
was developed by PaX Team <pageexec at freemail.hu>.
This is respin of this patch.

20130509: v2: (re-)add inline upon request.
