[PATCH] i2c: Rework client usage count, 3 of 3
Do not limit the usage count of i2c clients to 1. In other words, change the client usage count behavior from the old I2C_CLIENT_ALLOW_USE to the old I2C_CLIENT_ALLOW_MULTIPLE_USE. The rationale is that no driver actually needs the limiting behavior, and the unlimiting behavior is slightly easier to implement. Update the documentation to reflect this change.
