mfd: Inherit coherent_dma_mask from parent device
dma_mask and dma_parms are already inherited from the parent device but
dma_coherent_mask was left uninitialized (set to zero thanks to kzalloc).
Set sub-device coherent_dma_mask to its parent value to simplify
sub-drivers making use of dma coherent helper functions (those drivers
currently have to explicitly set the dma coherent mask using
dma_set_coherent_mask function).
