[Xen-devel] [PULL] xen: Fix xenpv machine initialisation

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

From: Anthony PERARD <anthony.perard@xxxxxxxxxx>

When using QEMU for Xen PV guest, QEMU abort with:
xen-common.c:118:xen_init: Object 0x7f2b8325dcb0 is not an instance of type 
generic-pc-machine

This is because the machine 'xenpv' also use accel=xen. Moving the code
to xen_hvm_init() fix the issue.

This fix 021746c131cdfeab9d82ff918795a9f18d20d7ae.
