arm64: dts: imx8qm-mek: switch Type-C connector power-role to dual
When attach to PC Type-A port, the USB device controller does not function
at all. Because it is configured as source-only and a Type-A port doesn't
support PD capability, a data role swap is impossible.
Actually, PTN5110THQ is configured for Source role only at POR, but after
POR it can operate as a DRP (Dual-Role Power). By switching the power-role
to dual, the port can operate as a sink and enter device mode when attach
to Type-A port.
Since the board design uses EN_SRC to control the 5V VBUS path and EN_SNK
to control the 12V VBUS output, to avoid outputting a higher VBUS when in
sink role, we set the operation current limit to 0mA so that SW will not
control EN_SNK at all.
