armv8: dts: ls1088a: add PSCI binding for LS1088A

This allows the use of PSCI calls to trusted firmware to
initiate reset and poweroff events with CONFIG_PSCI_RESET and
CONFIG_ARM_PSCI_FW. This is desirable, for example, if the target
board has implemented a custom reset or poweroff procedure in EL3.
