kinox: modify bc12 i2c port

The original BC12 I2C port setting the wrong port
I2C_PORT_USB_C0_PPC(NPCX_I2C_PORT2_0) will let the I2C protocol send
the wrong I2C port. And will cause the BC12 no function.

The BC12 correct port is I2C_PORT_USB_C0_BC12(NPCX_I2C_PORT6_1).



BUG=b:232033240
BRANCH=none
TEST=Kinox can get the USB2.0 device from type-c port.
