i386/pc: Drop pc_machine_kvm_type()

i386/pc: Drop pc_machine_kvm_type()

pc_machine_kvm_type() was introduced by commit e21be724eaf5 ("i386/xen:
add pc_machine_kvm_type to initialize XEN_EMULATE mode") to do Xen
specific initialization by utilizing kvm_type method.

commit eeedfe6c6316 ("hw/xen: Simplify emulated Xen platform init")
moves the Xen specific initialization to pc_basic_device_init().

There is no need to keep the PC specific kvm_type() implementation
anymore. So we'll fallback to kvm_arch_get_default_type(), which
simply returns 0.
