ASoC: SOF: amd: Optimize quirk for Valve Galileo

[ Upstream commit a13f0c3c ]

Valve's Steam Deck OLED is uniquely identified by vendor and product
name (Galileo) DMI fields.

Simplify the quirk by removing the unnecessary match on product family.

Additionally, fix the related comment as it points to the old product
variant.
