[PATCH i2c-next v4 1/3] dt-bindings: i2c: aspeed: Add 'timeout' property as an optional property

[Jae Hyun Yoo]

This commit adds 'timeout' property as an optional property which
can be used for setting 'timeout' value of 'struct i2c_adapter'.
With this patch, the bus timeout value can be set through this
DT property from the probing time of the module. Still the bus
timeout value can be set by an I2C_TIMEOUT ioctl on cdev at
runtime too.
