This patch series extends SED OPAL support: it adds IOCTL for setting the shadow
MBR done flag which can be useful for unlocking an OPAL disk on boot and it adds
IOCTL for writing to the shadow MBR. Also included are some minor fixes and
improvements.

This series is based on the original work done by Jonas Rabenstein which was
submitted in March 2018.[1]

There is a fork of sed-opal-temp that can use these new IOCTLs.[2] I tested
these on Samsung 840 EVO and 850 EVO drives, on x86-64 and arm64 systems.

The series applies on v5.0-rc4.

I'm resending as v4 as suggested by Scott Bauer.[3]

Changes from v3 to v4:
* added Reviewed-by from Scott, including for the patch 16/16 (details in
[3])
