Add amdzentemp from FreeBSD via Ian Clark.
man pages for amdsmn and amdzentemp.
Some clean-up on the HISTORY and AUTHORS sections, and addition of a BUGS
section to document the fact that we don't yet handle the required temp
offset, nor do we expose the available thermal-trip value.
Add missing article 'a'
KNF: Put back the blank line following the empty variable declarations
Put back the variable declaration, too, and mark it __diagused
Otherwise a DIAGNOSTIC kernel will complain about the variable being
undeclared.
Correct placement of __diagused attribute.
Modularize the amdsmn(4) driver, and update dependency for amdzentemp(4),
Create amdsmn(4) amd amdzentemp(4) modules for X86.

+.Nm amdzentemp
+.Nd AMD Zen CPU family on-die digital thermal sensor
+.Sh SYNOPSIS
+.Cd "amdzentemp* at amdsmnbus?"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the on-die digital thermal sensor present
+on AMD Ryzen CPUs
+.Pp
+These sensors provide 0.125\(deC accuracy.
+There is one sensor for each CPU socket.
+.Pp
+The
+.Nm
+driver reports temperatures through the
+.Xr envsys 4
+API.

+.Sh SEE ALSO
+.Xr amdtemp 4 ,
+.Xr envsys 4 ,
+.Xr envstat 8 ,
+.Xr powerd 8
+.Sh HISTORY
+The
+.Nm
+driver first appeared in
+.Ox 4.4
+named
+.Dq kate .
+It was then ported to
+.Nx 5.0
+under the name
+.Xr amdtemp 4 .
+The
+.Fx
+version of the driver was updated with support for newer AMD CPUs.
+For
+.Nx ,
+the support for the newer CPUs was separated into its own
+.Nm
+driver.
+.Sh AUTHORS
+.An -nosplit
+The
+.Nm
+driver was written by
+.An Constantine A. Murenin Aq Mt c...@openbsd.org
+whilst at the University of Waterloo.
+Porting of support for the newer AMD CPUs from
+.Fx
+was provided by
+.An Ian Clark .
+.Sh BUGS
+The temperature reading provided to
+.Xr envsys 4
+needs to have a CPU-dependent offset applied.
+For Ryzen X processors, the offset is 20\(deC, while for Threadripper
+processors an offset of 27\(deC is needed.
+.Pp
+The sensor has a thermal-trip value which should be retrieved and
+provided to
+.Xr envsys 4
+as the sensors critical-maximum value.
