[PATCH] KVM: arm64: Trival coding style fixes for all vgic-related files

From: Yanan Wang
Date: Mon Jun 14 2021 - 23:50:30 EST

These fixes introduce no functional change but just adjustment about
coding style issues for ARM64 vgic code. They mainly include identation
fix of function parameters/arguments, identation fix of structure
initialization, identation fix of comment, also the deletion of some
superfluous space lines.
