[PATCH v5 00/15] s390x: Add support for virtio-blk-pci IPL device

[jrossi@linux.ibm.com]

From: Jared Rossi <jrossi@linux.ibm.com>

This patch series introduces an IPLB subtype to support PCI devices, which may
be built if a device has been assigned a boot index and is identified as a PCI
device with a corresponding s390 PCI Bus device.

Boot support is only added for virtio-blk-pci at this time and is limited to
devices with an assigned bootindex.

A "loadparm" property is added to virtio-blk-pci boot devices on s390x.

A simple test to check basic functionality is added to the cdrom-tests in qtest.

Changes v4 -> v5:
    - Fix incorrect switch/case for virtio block device ID
    - Use target_s390x() instead of qemu_arch_available(QEMU_ARCH_S390X)
    - Properly denote switch fallthrough
    - Remove reduntant RC checks in PCI read/write
