[Skiboot] [PATCH 04/11] hdat: Grab vendor information from HDAT when available

[Vasant Hegde]

Latest spec added vendor information to IPL PARMS ntuple.
Grab this information when available instead of hardcoding
vendor name.

Also move vendor property code from vpd.c to iplparms
parsing function in spira.c.
