[U-Boot] [PATCH v3 3/3] x86: Show the un-relocated IP address in exceptions

[Simon Glass]

When trying to figure out where an exception has occured, the relocated
address is not a lot of help. Its value depends on various factors. Show
the un-relocated IP as well. This can be looked up in System.map directly.

- Replace 'regs->eip' with 'eip'
