hdat: handle ISDIMM SPD blobs
Previously the HDAT format was only ever used with IBM hardware so it
would store vital product data (VPD) blobs in the IBM ASCII Keyword VPD
format. With P9 HDAT is used on OpenPower machines which use Industry
Standard DIMMs that provide their product data through a "Serial Present
Detect" EEPROM mounted on the DIMM.
The SPD blob has a different format and is exported in the device-tree
under the "spd" property rather than the "ibm,vpd" property. This patch
adds support for recognising these blobs and placing them in the
appropriate DT property.
