drm/i915: Parse VBT data for lspcon
Many GEN9 boards come with on-board lspcon cards.
Fot these boards, VBT configuration should properly point out
if a particular port contains lspcon device, so that driver can
initialize it properly.
This patch adds a utility function, which checks the VBT flag
for lspcon bit, and tells us if a port is configured to have a
lspcon device or not.
V2: Fixed review comments from Ville
- Do not forget PORT_D while checking lspcon for GEN9
V3: Addressed review comments from Rodrigo
- Create a HAS_LSPCON() macro for better use case handling.
- Do not dump warnings for non-gen-9 platforms, it will be noise.
V4: Rebase
V5: Rebase
V6: Pass dev_priv to HAS_LSPCON() macro
