Subject: [PATCH 2/2] Input: bcm5974: Add another device ID for the mid-2013 Macbook Air

This patch adds a device ID found for mid-2013 Macbook Air 6,1 from
lsusb:

Bus 001 Device 003: ID 05ac:0290 Apple, Inc.

Since IDs already exist for this generation Macbook air as WELLSPRING8,
name this one WELLSPRING8A. This only adds an ANSI version since it's
device ID is only one less than the existing WELLSPRING8 IDs.
