Subject: [PATCH v5 2/8] clk: qcom: ipq5332: add gpll0_out_aux clock

From: Kathiravan Thirumoorthy <quic_kathirav@...cinc.com>

Add support for gpll0_out_aux clock which acts as the parent for
the following networking subsystem (NSS) clocks.

	ce_clk
	cfg_clk
	eip_bfdcd_clk
	port1_rx_clk
	port1_tx_clk
	port2_tx_clk
	ppe_clk
