clk: qcom: ipq5332: mark GPLL4 as ignore unused temporarily

Browse Source 
Clock framework disables the GPLL4 source since there are no active users
for this source currently. 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.
