The resume functionality of maxim gmsl dp serializer
driver calls init routine. Function incorrectly treats
register value as return value and shows error message
in logs. Removing return value check from register read
during init fixes this issue.

This change adds GMSL3 support to maxim dp serializer
driver. The property is set in device tree which is if true,
then PAM4 mode is enabled and 12 Gbps link rate is set.
GMSL3 also needs to have FEC enabled. This change also
adds that support.
Device tree need to have "enable-gmsl3" property to be set
to get GMSL3 enabled.
When GMSL3 is enabled, it will enable GMSL-FEC by default.
GMSL-FEC can only be enabled by setting propery "enable-gmsl-fec".

Upstream Linux commit ed5c2f5fd10d ("i2c: Make remove callback return
void") in Linux v6.1, updates the i2c remove callback to prototye to
return void instead of int. This is causes the Maxim DP Serialize driver
build to fail for Linux v6.1. Update this driver to fix the build for
Linux v6.1.

This change removes worker thread from serializer driver
which waits on both links to lock. If both links are not set
via DTS entry then it does not proceed further which causes
no video output.
As it is possible that one link can be connected to deserializer,
this does not require the worker to wait on link locks. So removing
worker thread and enabling video immediately fixes this issue.

When ruining a few hundred loops of link training between the SOC
and the serializer, we are seeing unexpected HPD_IRQ being triggered
by the MAX96745/96851 serializers due to "Branch sink count change"
event. Till we figure out why this is happening, disable this
interrupt source.

This change enables external video CRC check for
Maxim DP Serializer.
This change -
1. Enable video line CRC functionality by setting specific register bit.
2. Add interrupt handler check for remote CRC check failure.
3. Reverse GPIO tunnel and remote error check is already set.
4. If there are CRC error across GMSL link then dmesg spew will indicate it.
Verification -
1. Play some GFX application and view on monitor.
2. At DES side, using GUI, For register INTR8, set bit ERR_TX_EN to 1.
3. Clear exiting dmesg using "dmesg --clear"
4. On SER, using i2ccmd tool, Set bit LINE_CRC_EN to 0 at register 0x100.
5. Confirm on dmesg for error message like - "Remote deserializer error detected"

This change enables internal video CRC check for
Maxim DP Serializer.
1. This sets the bit to enable CRC functionality
and then add handlers for ERRB CRC errors.
2. Reading register clears the error.
3. Error can be injected using i2c tool to write
error inject bit in register.
Below is flow to verify CRC functionality
1. Run GFX application like bubble
2. Read VTX41 register and confirm VID_ASIL_CRC_ERR bit is not set
3. Inject error by setting bit VID_ASIL_INJ_ERR.
4. Verify dmesg errors.

Fix the build for kernels prior to v5.15 by not attempting to access
the return value. Finally, for kernels v5.15 and newer, do not ignore
the return value and report an error if device_add_disk() fails.
