Make SMBIOS table pass MS SVVP test

Make SMBIOS table pass MS SVVP test

Microsoft SVVP (Server Virtualization Validation Program) expects
arbitrary SMBIOS field to have certain values otherwise it fails.
We all want to make Microsoft happy don't we? So lets put values MS
expects in there.

Values modified by the patch:
 Type 0:
  Bit 2 of byte 2 must be 1
 Type 1:
  Manufacturer/product string should not be empty
 Type 3:
  Manufacturer string should not be empty
 Type 4:
  Processor manufacturer should no be empty
  Max/current CPU speed shouldn't be unknown
 Type 16:
  Memory should have error correction.

---

v1->v2:
 Use CONFIG_APPNAME instead of open coding strings
 Use snprintf.
