[PATCH v2 11/12] hw/block/nvme: bump to v1.4

[Klaus Jensen]

From: Klaus Jensen <k.jensen@samsung.com>

With the new CMB logic in place, bump the implemented specification
version to v1.4.

This requires adding the setting the CNTRLTYPE field and modifying the
VWC field since 0x00 is no longer a valid value for bits 2:1.
