drm/i915: Write AVI infoframes for MCA LSPCON
LSPCON is a DP branch device, so LSPCON vendors define
specific methods to pass AVI infoframes to the the chip.
This patch adds:
- a generic wrapper function for writing AVI infoframes for
all LSPCON devices.
- a vendor specific function to wrire AVI infoframes into
MCA LSPCON devices.
