J722S SOC has two usb controllers USB0 and USB1. USB0 is brought out on the EVM as a stacked USB connector which has one Type-A and one Type-C port. These Type-A and Type-C ports are connected to MUX so only one of them can be enabled at a time. Commit under Fixes, tries to enable the USB0 instance of USB to interface with the Type-C port via the USB hub, by configuring the USB2.0_MUX_SEL to GPIO_ACTIVE_HIGH. But it is observed on J722S-EVM that Type-A port is enabled instead of Type-C port. Fix this by setting USB2.0_MUX_SEL to GPIO_ACTIVE_LOW to enable Type-C port.
