efi_loader: migrate SMBIOS 3.0 entry point structure for measurement
Current U-Boot only supports the SMBIOS 3.0 entry point structure.
TCG2 measurement code should migrate to SMBIOS 3.0 entry
point structure.
efi_selftest tcg2 test also needs to be updated, and expected
PCR[1] result is changed since guid for SMBIOS EFI system table
uses different guid SMBIOS3_TABLE_GUID instead of SMBIOS_TABLE_GUID.
