configs: j721e_evm_r5_defconfig: Remove SPL multi-DTB FIT support

The SPL FIT will only have one DTB, so remove support for multi-DTB. This
also removes an early access to EEPROM used to select the DTB that is not
valid in SPL at the point at which it is accessed, that always returns
false for GP devices and causes a firewall expection on HS.
