Subject: [PATCH] cpufreq: arm-big-little: Make driver dependent on CONFIG_BIG_LITTLE

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'

Reported-by: Russell King <linux@....linux.org.uk>
