clk: scmi: Fix priv initialization in scmi_clk_gate()

In scmi_clk_probe(), in case of CLK_CCF is not enabled, parent private
data is not set, so in scmi_clk_gate(), an uninitialized priv struct is
retrieved.

SCMI request is performed either using scmi_clk_state_in_v1 or
scmi_clk_state_in_v2 struct depending of the unpredictable value of
priv->version which leads to error during SCMI clock enable.

Issue detected on STM32MP157C-DK2 board using the SCMI device tree
stm32mp157c-dk2-scmi.dts.
