drm/bridge: dw-hdmi: Adapt to bridge API change

Commit fbc4572e9c48e45b ("drm/bridge: make bridge registration independent of
drm flow") introduced some drm/bridge API modifications. Make the necessary
changes so that we can avoid the build breakage:

drivers/gpu/drm/bridge/dw_hdmi.c: In function 'dw_hdmi_bridge_destroy':
drivers/gpu/drm/bridge/dw_hdmi.c:1378:2: error: implicit declaration of function 'drm_bridge_cleanup' [-Werror=implicit-function-declaration]
drivers/gpu/drm/bridge/dw_hdmi.c: At top level:
drivers/gpu/drm/bridge/dw_hdmi.c:1471:2: error: unknown field 'destroy' specified in initializer
drivers/gpu/drm/bridge/dw_hdmi.c: In function 'dw_hdmi_register':
drivers/gpu/drm/bridge/dw_hdmi.c:1535:2: error: implicit declaration of function 'drm_bridge_init' [-Werror=implicit-function-declaration]
