drm/i915/audio: Use BIOS provided value for RKL HDA link
[ Upstream commit ffac30be2a06b2516b2ce2afa2dcb2cf8af65a52 ]
Commit 989634fb49ad ("drm/i915/audio: set HDA link parameters in
driver") makes HDMI audio on Lenovo P350 disappear.
So in addition to TGL, extend the logic to RKL to use BIOS provided
value to fix the regression.
