drm/i915/display: update to the BW buddy configuration

Browse source

Bspec has been updated for xe2_lpd+ platforms on how to handle
the bw buddy programming in case no matching memory configuration
is found w.r.t the current page mask table. The recommendation
is to keep the default settings for the related registers as it
is without explicitly disabling the bw buddy.

v2: removed extra explanation

v3: fixed typo in commit message
