[Qemu-devel] [PATCH 32/77] ppc/xics: Replace "icp" with "xics" in most places

[Benjamin Herrenschmidt <benh@kernel.crashing.org>]

The "ICP" is a different object than the "XICS". For historical reasons,
we have a number of places where we name a variable "icp" while it contains
a XICSState pointer. There *is* an ICPState structure too so this makes
the code really confusing.

This is a mechanical replacement of all those instances to use the name
"xics" instead. There should be no functional change.
