cpufreq: apple-soc: Set fallback transition latency to APPLE_DVFS_TRANSITION_TIMEOUT

The driver already assumes transitions will not take longer than
APPLE_DVFS_TRANSITION_TIMEOUT in apple_soc_cpufreq_set_target(), so it
makes little sense to set CPUFREQ_ETERNAL as the transition latency
when the transistion latency is not given by the opp-table.
