Benjamin Herrenschmidt 80546ac513 powerpc/powernv: Add support for indirect XSCOM via debugfs ...

Indirect XSCOM addresses normally have the top bit set (of the 64-bit
address). This doesn't work via the normal debugfs interface, so we use
a different encoding, which we need to convert before calling OPAL.
