This enables on both multi_v7_defconfig and bcm2835_defconfig the new
firmware based clock and cpufreq drivers for the Raspberry Pi platform.

In the case of bcm2835_defconfig, as the cpufreq subsystem was disabled,
the conservative governor was selected as default since it better
handles the high frequency transition latency.

Changes since v2:
  - Change default governor to conservative in bcm2835_defconfig
  - Set all as builtin in bcm2835_defconfig
