Update decode-dimms to 2019-10-02

Upstream changes.  (Note that some of these don't really affect to NetBSD,
but are included anyway for reducing differences with the upstream copy.)

	Detect and report truncated input files
	   If using the wrong driver, or if reading from a truncated dump
	   file, make sure we don't attempt to use data bytes beyond what
	   is available. Doing so would spit pages of cryptic warnings to
	   the user, explicit error messages are much better.

	Print kernel driver used
	   When not reading from dump files, print which kernel driver is
	   being used.  This will help spot setup mistakes where the legacy
	   eeprom driver stole EEPROMs from the ee1004 driver for DDR4
	   memory.

	Print DDR memory speed in MT/s not MHz
	   Because it is DDR memory, transaction rate is twice the actual
	   clock speed. What the user is interested in is MT/s, and that's
	   the number we display, so use the right unit.

	Add DDR5 memory types to the list
	   No information available yet about the contents of the DDR5 SPD
	   EEPROMs but we can already report the basic memory type.

	Decode manufacturing data for LPDDR3
	   I assume the manufacturing data format for LPDDR3 is the same
	   as regular DDR3.

	Fix the version string
	   We moved away from Subversion long ago, so $Revision$ and $Date$
	   are no longer being resolved. Just use the version of i2c-tools
	   itself.

	Point the user to the right driversHEADmaster
	   The header comment only mentioned the legacy eeprom driver, while
	   the at24 and ee1004 drivers should be used nowadays.
