configs: am62x_evm_a53_defconfig: Disable semi-functional PSCI reset support

At this point, system shutdown is not supported by the DM firmware
that TF-A calls. As we can't de-select only this feature[1], declare
complete PSCI reset support as non-functional so that we don't signal
incomplete support to the OS via EFI runtime services. This makes
power-off under Linux work again when booting via EFI.
