drivers/i2c/generic: Add config for marking device as probed
Add a config option to the generic I2C device driver to indicate to
the OS that this device should be probed before being added.
This can be used to provide ACPI device instantiations to devices that
may not actually exist on the board. For example, if multiple trackpad
vendors are supported on the same board they can both be described in
ACPI and the OS will probe the address and load the driver only if the
device responds to the probe at that address.
