[PATCH AUTOSEL 5.10 27/56] ASoC: Intel: bytcr_rt5640: Add new BYT_RT5640_NO_SPEAKERS quirk-flag

From: Hans de Goede <hdegoede@xxxxxxxxxx>

[ Upstream commit 1851ccf9e155b2a6f6cca1a7bd49325f5efbd5d2 ]

Some devices, like mini PCs/media/top-set boxes do not have any speakers
at all, an example of the is the Mele PCG03 Mini PC.

Add a new BYT_RT5640_NO_SPEAKERS quirk-flag which when sets does not add
speaker routes and modifies the components and the (optional) long_name
strings to reflect that there are no speakers.
