Subject: [PATCH v4 2/3] mpc8xxx: assume unregistered DIMM for invalid SPD module_type

The generic Freescale DDR SDRAM SPD parsing code fails when the SPD's
module_type field has an unknown value. In this case, we should assume
that the memory module is an unregistered DIMM (the usual case).

The DDR3 DIMM shipped with the Freescale COM Express P2020 Evaluation
Kit has the module_type field set to 0x08. This is an unknown value in
all documentation I can find online.

Isn't 0x08 72b-SO-UDIMM?
