The alternative is to move them into the source file that uses then,
but they are large and intrusive, so that strategy is being avoided.

Fixes the following W=1 kernel build warning(s):

 drivers/gpu/drm/vc4/vc4_hdmi_regs.h:282:39: warning: ‘vc5_hdmi_hdmi1_fields’ defined but not used [-Wunused-const-variable=]
 drivers/gpu/drm/vc4/vc4_hdmi_regs.h:206:39: warning: ‘vc5_hdmi_hdmi0_fields’ defined but not used [-Wunused-const-variable=]
 drivers/gpu/drm/vc4/vc4_hdmi_regs.h:145:39: warning: ‘vc4_hdmi_fields’ defined but not used [-Wunused-const-variable=]
