Ley Foon Tan 9e6082198a reset: socfpga: Poll for reset status after deassert reset
In Cyclone 5 SoC platform, the first USB probing is failed but second
probing is success. DWC2 USB driver read gsnpsid register right after
de-assert reset, but controller is not ready yet and it returns gsnpsid 0.
Polling reset status after de-assert reset to solve the issue.

Retry with this fix more than 10 times without issue.
