vTPM/TPM2: TPM 2.0 takes ownership and create SRK

TPM2_CreatePrimary is used to create a Primary Object under one of
the Primary Seeds or a Temporary Object under TPM_RH_NULL. The command
uses a TPM2B_PUBLIC as a template for the object to be created. The
command will create and load a Primary Object. The sensitive area is
not returned. Any type of object and attributes combination that is
allowed by TPM2_Create() may be created by this command. The constraints
on templates and parameters are the same as TPM2_Create() except that a
Primary Storage Key and a Temporary Storage Key are not constrained to
use the algorithms of their parents.
