zephyr: Automatically detect shared I2C ports
Delete the "physical-port" node from named-i2c-ports, and automatically
detected when multiple children point to the same I2C bus.
This ensures that the I2C bus locking always blocks all matching I2C
nodes, without the user needing to specify this relationship manually
in the devicetree.
BUG=none
BRANCH=none
TEST=Dump out i2c_physical_ports[] on herobrine.
