[PATCH 07/12] xen/arm: new vgic: rename vgic_cpu/dist_base to c/dbase

[Stefano Stabellini <sstabellini@kernel.org>]

To be uniform with the old vgic. Name uniformity will become immediately
useful in the following patch.

In vgic_v2_map_resources, use the fields in struct vgic_dist rather than
local variables.
