[PATCH i2c-next v3 1/3] dt-bindings: i2c: aspeed: Add 'timeout' property as an optional property

[Jae Hyun Yoo]

This commit adds 'aspeed,timeout' property as an optional property
which can be used for setting 'timeout' value of
'struct i2c_adapter'. With this patch, the timeout value can be
set through an I2C_TIMEOUT ioctl on cdev, or through this optional
DT property.
