cpufreq: arm_big_little: fix module license spec
Having no license specification in a module taints the kernel during load
with:
arm_big_little: module license 'unspecified' taints kernel.
and also the linker doesn't allow it to make use of GPL-exported symbols
which in this case also results in errors like:
arm_big_little: Unknown symbol cpufreq_register_driver (err 0)
. The header of the driver specifies a GPL v2 license, so note that
accordingly. While at it also add a description and an author and fix
the license in a companion file to explicit v2.
