[PATCH 1/7] i2c: provide i2c_adapter_set_node()

[Bartosz Golaszewski <bartosz.golaszewski@oss.qualcomm.com>]

Provide a wrapper around device_set_node() that takes the i2c_adapter as
argument. This allows us to hide more dereferencing of the embedded
struct device as part of working towards fixing the object lifetime
issues in i2c.
