psci_update_dt() is also required if CONFIG_ARMV8_PSCI is set, that is, if u-boot is the PSCI provider. Guard the check which is intended to call into the PSCI implementation in the secure firmware, by the proper macro SEC_FIRMWARE_ARMV8_PSCI.
Mark the function as weak because - unfortunately - there is already a stub of the same function in arch/arm/mach-rmobile/psci-r8a779a0.c which does not the same as the common one.
