[PATCH 6/8] drm/meson: dw-hdmi: annotate dw_hdmi_dwc_write_bits() with __maybe_unused

Building with clang and and W=1 leads to warning about unused
dw_hdmi_dwc_write_bits(). Fix by annotating it with __maybe_unused.

See also commit 6863f5643dd7 ("kbuild: allow Clang to find unused static
inline functions for W=1 build").
