mainboard/google/poppy: Generate required nhlt table
poppy board uses Maxim 98927 speaker codec and Realtek RT5663 for heaset. Select the apropriate NHLT blobs to be packaged in CBFS. Also, generate the required ACPI NHLT table for codec and the supported topology in poppy.
BUG=None BRANCH=None TEST=With the required driver support in kernel verify that the Audio plays on on-board speakers and headset, recording works from on-boards mics and headset mics.
