dpcm_end_walk_at_be() stops the graph walk when first BE is found for
the given FE component. In a component model we may want to connect
multiple DAIs from different components. A new flag is introduced in
'snd_soc_card', which when set allows DAI/component chaining. Later
PCM operations can be called for all these listed components for a
valid DAPM path.

(cherry picked from commit aa293777bfeb75fb8872565ef99cc0e8b98b5c7d)
[ refactored to avoid breaking KMI ]
ALSA machine driver can setup component_chaining like below code slice.
static int my_board_late_probe(struct snd_soc_card *card)
{
struct snd_soc_card_ext *card_ext =
container_of(card, struct snd_soc_card_ext, card);
card_ext->component_chaining = 1;
return 0;
}
static struct snd_soc_card my_board_card = {
.name = MY_BOARD_NAME,
.owner = THIS_MODULE,
.dai_link = my_board_dai_links,
.num_links = ARRAY_SIZE(my_board_dai_links),
.late_probe = my_board_late_probe,
};
