Documentation: Correct the possible MDS sysfs values

BugLink: https://bugs.launchpad.net/bugs/1829050

commit ea01668f9f43021b28b3f4d5ffad50106a1e1301 upstream

Adjust the last two rows in the table that display possible values when
MDS mitigation is enabled. They both were slightly innacurate.

In addition, convert the table of possible values and their descriptions
to a list-table. The simple table format uses the top border of equals
signs to determine cell width which resulted in the first column being
far too wide in comparison to the second column that contained the
majority of the text.

x86/mds: Add MDSUM variant to the MDS documentation

BugLink: https://bugs.launchpad.net/bugs/1829050

commit e672f8bf71c66253197e503f75c771dd28ada4a0 upstream

Updated the documentation for a new CVE-2019-11091 Microarchitectural Data
Sampling Uncacheable Memory (MDSUM) which is a variant of
Microarchitectural Data Sampling (MDS). MDS is a family of side channel
attacks on internal buffers in Intel CPUs.

MDSUM is a special case of MSBDS, MFBDS and MLPDS. An uncacheable load from
memory that takes a fault or assist can leave data in a microarchitectural
structure that may later be observed using one of the same methods used by
MSBDS, MFBDS or MLPDS. There are no new code changes expected for MDSUM.
The existing mitigation for MDS applies to MDSUM as well.
