Subject: [PATCH 03/26] ALSA: hda: cs35l41: Remove Set Channel Map api from binding

From: Stefan Binding <sbinding@...nsource.cirrus.com>

This API was required for CLSA0100 laptop, which did not
have correct properties inside ACPI. The required values
are now hardcoded inside the driver so this is no longer
needed.
Without this api, there CLSA0100 can now use the generic
cs35l41 fixup, like the other laptops.
All other laptops will read the Speaker Position from
ACPI and set the channel map from within the driver.
