From: Frank Wang <frank.w...@rock-chips.com>
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.
