usb: gadget: dwc2_udc_otg: modified the check condition for max packet size of ep_in in high speed

Browse Source 
In current high speed fastboot, fs_ep_in.wMaxPacketSize is configured 64 bytes
as default, as a result, it failed to match the size at initialization stage in
usb controller.
Actually, hardware can support less than or equal to 512 bytes in high speed mode,
so I changed the condition from  '!=' to '>' to fix this issue.
