gcc_qdss_tsctr_clk_src (enabled in the boot loaders and dependent
on gpll4_main) was not registered as one of the ipq5332 clocks.
Hence clk_disable_unused() disabled 'gpll4_main' assuming there
were no consumers for 'gpll4_main' resulting in system freeze or
reboots.
After registering gcc_qdss_tsctr_clk_src, CLK_IGNORE_UNUSED can
be removed from gpll4_main.
