[PATCH 1/4] ACPI: scan: Add CLSA0102 to the serial bus ignore list

[Ilya Pavlukhin]

The Lenovo Yoga Slim 7 Carbon 14ACN6 (82L0) describes the two CS35L41
amplifiers of its bass speakers as a single ACPI node, HID CLSA0102,
with two I2cSerialBusV2 resources (0x40 and 0x41), like CLSA0100 and
CLSA0101 on the Legion 7. Skip the default I2C enumeration so that
serial-multi-instantiate can create a client for each amplifier.
