[PATCH 1/5] lightnvm: change vendor and dev id for qemu

[Matias BjÃrling]

The QEMU NVMe simulator uses the intel vendor, qemu device id, and the
first vendor specific byte to identify a lightnvm compatible nvme
instance.

Instead of using the Intel NVMe QEMU instance vendor and device id,
let's use a preallocated from CNEX Labs instead. This lets us uniquely
identify a QEMU lightnvm device without breaking other vendor specific
work in the qemu device driver.
