The Tegra234 SoC uses Cortex-A78AE cores, not Cortex-A78. Update the
compatible string for all CPU nodes to match the actual hardware.
Tegra234 hardware reports:
# head /proc/cpuinfo | egrep 'implementer|part'
CPU implementer : 0x41
CPU part : 0xd42
Which maps to (from arch/arm64/include/asm/cputype.h):
#define ARM_CPU_IMP_ARM 0x41
#define ARM_CPU_PART_CORTEX_A78AE 0xD42
Fixes: a12cf5c339b08 ("arm64: tegra: Describe Tegra234 CPU hierarchy")
