zephyr: i2c: Add dynamic-speed flag to named-i2c node
Add a property dynamic-speed to a i2c-named dts node. It informs that
the i2c speed of the i2c node can be changed in run-time with a console
command or a host command.
BUG=b:201408931
TEST=zmake testall & verify that i2c freq can be changed for marked
ports
