powerpc/xive: Fix compile when !CONFIG_PPC_POWERNV.
The automatic "save & restore" of interrupt context is a POWER10/XIVE2
feature exploited by KVM under the PowerNV platform. It is not
available under pSeries and the associated toggle should not be
exposed under the XIVE debugfs directory.
Introduce a platform handler for debugfs initialization and move the
'save-restore' entry under the native (PowerNV) backend to fix compile
when !CONFIG_PPC_POWERNV.
Fixes: 1e7684dc4fc7 ("powerpc/xive: Add a debugfs toggle for save-restore")
