Enable the options needed to test CPU hotplug latency

Enable CONFIG_HOTPLUG in linaro-base.conf as all Linaro kernels should
have it. Enabling CONFIG_DEBUG_FS and CONFIG_FUNCTION_TRACER add no
runtime slowdown if not used, so having them in linaro-base.conf is OK
too. Now that CONFIG_HOTPLUG and CONFIG_DEBUG_FS are in linaro-base.conf,
remove them from ubuntu.conf.
