[PATCH] board: ti: am62x: beagleplay: Disable semi-functional PSCI reset support

From: Jan Kiszka <jan.kiszka at siemens.com>

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, 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.
