[PATCH v2 1/3] drm/bridge: dw-hdmi-i2s: annotate hdmi_read() with __maybe_unused

[Jani Nikula]

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

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