[PATCH 3/4] nvme: lightnvm: trace opcode name

[minwoo.im.dev@gmail.com (Minwoo Im)]

This patch moved opcode enum values to nvme.h to make it support for
command trace with opcode name istead of raw opcode value.

Example of Vector Chunk Read:
	... cmd=(0xe2 cdw10=00 00 00 00 00 00 00 00 00 ...

It would be like:
	... cmd=(nvme_nvm_admin_identity cdw10=00 00 00 00 00 00 00 00 00 ...

Although OCSSD 1.2 has been deprecated, we have the codes for 1.2 so
that this kind of traces might be deprecated later time.
