drm/i915: Add lspcon support for I915 driver
This patch adds a new file, to accommodate lspcon support
for I915 driver. These functions probe, detect, initialize
and configure an on-board lspcon device during the driver
init time.
Also, this patch adds a small structure for lspcon device,
which will provide the runtime status of the device.
V2: addressed ville's review comments
- Clean the leftover macros from previous patch set
V3: Rebase
V4: addressed ville's review comments
- make internal functions static
- remove lspcon_detect_identifier, make it inline with lspcon_probe
- remove is_lspcon_active function
- remove force check while setting a lspcon mode
V5: Rebase
V6: Pass dev_priv to IS_GEN9 check
