While we expect to call a pointer to a valid FDT (or NULL) as the platform parameter to an ATF, some ATF versions are not U-Boot aware and have an insufficiently robust (or an overzealour) parameter validation: either way, this may cause a hard-stop with uncooperative ATF versions.
This change adds the option to suppress passing a platform parameter and will always pass NULL.
Debug output from ATF w/ this option disabled (i.e. default): INFO: plat_param_from_bl2: 0x291450 Debug output from ATF w/ this option enabled: INFO: plat_param_from_bl2: 0
