When core soft reset timeout happens, pullup doesn't check for the
return value and proceeds to setup event buffers and starts the
controller.
In this scneario, it is observed sometimes that the GEVTADDR LO/HI
registers read zero while we are setting the run stop bit and we end
up accessing address 0x00 leading to a crash. This series tries to
address this issue by handling the timeout and return back appropriate
error code to configfs for it to retry enumeration if it chooses to.
