Subject: linux-raspberrypi: Drop unnecessary configurations

KERNEL_ENABLE_CGROUPS: This is obsolete, all required config options for cgroups
are enabled by default.

KERNEL_INITRAMFS: Some of the config options we set are already enabled by
default.

UDEV_GE_141: This is long obsolete and all the required config options are
already set in the defconfig.

ARM_KEEP_OABI: AEABI=y and OABI_COMPAT=n are already set in the defconfig.

CONFIG_LOCALVERSION_AUTO: This setting is already disabled in the defconfig.
