meta-facebook: bletchley15: fix switch usb mux issue
After switching usb between from sled 1 to sled 4 muliple times, usb driver may failed to detect usb hub, thereore, can not detect mac mini.
There are 2 ways to fix them:
1. There are four gpio to determinne which sled switch to BMC, if we set those gpio sequentially (not set them at the same time), it may cause usb driver at unkonown stage while setting those gpio. Therefore, use devemem command to set those gpio at once.
2. If we rebind the usb driver after switching usb mux, it may help usb driver re-detect usb hub if usb driver crash.
