[PATCH v2 0/4] cpufreq: bmips-cpufreq: Add CPUfreq driver for Broadcom's BMIPS SoCs

This series adds a CPUfreq driver for the BMIPS SoCs. In the first
iteration only BMIPS5xxx SoCs are supported.

The very first patch contains updates to bmips_stb_defconfig that are
unrelated to this series. Looks like bmips_stb_defconfig hasn't been
updated in a while. I didn't want to mix those changes with the CPUfreq
related ones, so that patch now comes first in the series and is
independent of the CPUfreq related changes to bmips_stb_defconfig
(patch 4/4).

This series is based on pm/linux-next.

Changes since v1:
- based on pm/linux-next rather than 4.10-rc1
- sanitized bmips_stb_defconfig by running "make savedefconfig"; this
also lead to an additional patch (1/4), which contains non-CPUfreq
related updates that "make savedefconfig" performed
- use gobal variable to store driver data rather than policy->driver_data
- got rid of some code as a result of using said global variable
- kzalloc -> kmalloc
- removed policy->freq_table = NULL;
