uThis patch adds support to DB820c machine driver.
Drop 'u' and expand the message to claim that this is the machine driver
for 8996, used by the db820c.

Are there any differences between the DAI links of apq8096 and msm8996?
This driver is more of board specific,
Am not 100% sure about msm8996, on apq8096 in particularly on db820c we
got hdmi and analog audio connected via slimbus and also I2S on lowspeed
connector.

No need to print in both parse_of() and here.
yep.

This isn't an error, skip the print here.
