Subject: [PATCH v4 6/7] ARM: defconfig: enable cpufreq driver for RPi
Date:   Wed, 12 Jun 2019 20:24:58 +0200

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
