[PATCH v4 4/4] hw/i386/sgx: Attach SGX-EPC objects to machine

["Philippe Mathieu-Daudé via" <qemu-devel@nongnu.org>]

Previously SGX-EPC objects were exposed in the QOM tree at a path

  /machine/unattached/device[nn]

where the 'nn' varies depending on what devices were already created.

With this change the SGX-EPC objects are now at

  /machine/sgx-epc[nn]

where the 'nn' of the first SGX-EPC object is always zero.
