[PATCH v4 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 v3 -> v4:
    - Reset virtio device after failed boot (not PCI specific)
    - Use defined constant for CLP block size
    - Enable PCI bus master bit
    - Refactor where some byte swaps happen
    - Fix an incorrect offset during PCI config read
    - Update maintainers when moving CLP definitions
    - Improve various error messages to include more info/codes
