    arm64: dts: imx8mn-var-som: add missing pull-up for onboard PHY reset pinmux
    
    [ Upstream commit 253be5b53c2792fb4384f8005b05421e6f040ee3 ]
    
    For SOMs with an onboard PHY, the RESET_N pull-up resistor is
    currently deactivated in the pinmux configuration. When the pinmux
    code selects the GPIO function for this pin, with a default direction
    of input, this prevents the RESET_N pin from being taken to the proper
    3.3V level (deasserted), and this results in the PHY being not
    detected since it is held in reset.
    
    Taken from RESET_N pin description in ADIN13000 datasheet:
        This pin requires a 1K pull-up resistor to AVDD_3P3.
    
    Activate the pull-up resistor to fix the issue.
