drm/ingenic: Silence uninitialized-variable warning

Browse Source 
Silence compiler warning about used but uninitialized 'ipu_state'
variable. In practice, the variable would never be used when
uninitialized, but the compiler cannot know that 'priv->ipu_plane' will
always be NULL if CONFIG_INGENIC_IPU is disabled.

Silence the warning by initializing the value to NULL.
