The driver prints pcsr twice: the first time it uses specifier %px to print hexadecimal pcsr value and the second time uses specifier %pS for output kernel symbols. As suggested by Kees, using %pS should be sufficient and %px isn't necessary; the reason is if the pcsr is a kernel space address, we can easily get to know the code line from %pS format, on the other hand, if the pcsr value doesn't fall into kernel space range (e.g. if the CPU is stuck in firmware), %pS also gives out pcsr hexadecimal value. So this commit removes useless %px and update section "Output format" in the document for alignment between the code and document.
