arm64: dts: imx8mn-var-som-symphony: adapt FEC pinctrl for SOMs with onboard PHY
The VAR SOM symphony carrier board can be used with SOMs which have a
soldered ethernet PHY onboard and with SOMs which don't have one.
For SOMs with an onboard PHY, the PHY on the cartrier board is not
used, and GPIO1_IO9 is used as a reset line to the onboard PHY.
For SOMs without an onboard PHY, the PHY on the carrier board is
used. For this configuration, pca9534 GPIO 5 (located on the carrier
board) is used as a reset line to the PHY, and GPIO1_IO9 is not
used.
GPIO1_IO9 is not connected to any user-accessible pins or functions,
and leaving it enabled in the mux pinctrl for both configurations is
safe.
