zephyr: I2C cleanup
Zephyr does not use the GPIO based I2C recovery. Delete
i2c_get_line_levels() and I2C_CONFIG_GPIO() as these symbols are no
longer referenced.
Move a the DT_NODE_EXISTS to the top of the file as the named-i2c-ports
node is need throughout this file.
BUG=none
BRANCH=none
TEST=zmake testall
