Subject: [PATCH v6 3/5] clk: qcom: ipq5332: Register gcc_qdss_tsctr_clk_src

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.

Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@...aro.org>
Fixes: 3d89d52970fd ("clk: qcom: add Global Clock controller (GCC) driver for IPQ5332 SoC")
Signed-off-by: Varadarajan Narayanan <quic_varada@...cinc.com>

v5: Add 'Reviewed-by: Dmitry Baryshkov'
v4: Move gpll4_main change that removes CLK_IGNORE_UNUSED to next patch
