This patch exports the NVMe Controller CSTS register via sysfs.  This
feature can be used by userland executables that accessed CSTS and
possibly other registers by mapping them into user space.  Since this ability
may not always available, exporting certain registers via sysfs provides
a safe/read-only way to access registers from outside the kernel.

So what is this application doings with it?  Should we just have a
ready attribute instead of exporting a raw register encoding?

Was using nvme-cli show-regs to manage nvme devices. This is no longer an option.
