From: Brent Lu <brent.lu@xxxxxxxxx>
Add an new field link_id_overwrite to sof_card_private structure to
support machine drivers which DAI link ID is fixed number or
discontinue (i.e. no-codec boards). If this field is zero, DAI array
index will be used as link ID. Otherwise the value extracted from
link_id_overwrite will be used.
The field link_id_overwrite is supposed to be initialized by
SOF_LINK_IDS macro like following example.
ctx->link_id_overwrite = SOF_LINK_IDS(HEADPHONE_BE_ID, \
DMIC01_BE_ID, \
DMIC16K_BE_ID, \
IDISP_HDMI_BE_ID, \
SPK_BE_ID, \
BT_OFFLOAD_BE_ID, \
HDMI_IN_BE_ID)
An exception is that, if you use link_order_overwrite to overwrite
DAI link order, then you need to use the same order to build
link_id_overwrite variable as well.
