Some of the clocks initialized by the bootloaders uses the GPLL4 as the source. Due to this, when the GPLL4 is disabled by the clock framework, system is going for the reboot. To avoid this, mark the GPLL4 as ignore unused so that clock framework doesn't disable it. Once the users of this source is enabled, we can get rid of this flag.
