Create a char device per NVMe namespace. This char device is always
initialized, independently of whether the features implemented by the
device are supported by the kernel. User-space can therefore always
issue IOCTLs to the NVMe driver using the char device.

The char device is presented as /dev/nvme-generic-XcYnZ. This naming
scheme follows the convention of the hidden device (nvmeXcYnZ). Support
for multipath will follow.

Do we perhaps want to put these new character devices inside a subdir?
e.g. /dev/nvme/nvme-generic-XcYnZ ?

Otherwise it feels like doing such a simple thing as ls -al /dev/nvme*
will show a lot of devices because of these new specialized char devices.


Kind regards,
