mainboard/google/poppy: Generate required nhlt table
poppy board uses Maxim 98927 speaker codec and Realtek RT5663
for headset. 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=chrome-os-partner:62051
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-board mics and headset mics.
