arm_big_little cpufreq driver is only used for ARM bigLITTLE platforms and hence must be dependent on CONFIG_BIG_LITTLE.
This was highlighted by Russell earlier when he reported this issue:
drivers/built-in.o: In function `bL_cpufreq_set_rate': powercap_sys.c:(.text+0x5ed9a0): undefined reference to `bL_switch_request_cb'
