Subject: [PATCH v1 0/2] Revert vendor property from anx7625 bindings

An issue[1] related to how the V4L2_FWNODE_BUS_TYPE_PARALLEL flag is mis-used
was found in recent addition to the anx7625 driver.

In order to not introduce this issue into the ABI, let's revert the changes
to the anx7625 dt-binding related to this.

If this is enough to avoid the wrong bus-type becoming an ABI, even if
the corresponding driver support isn't reverted, then, for the whole
series,
