soc: qcom: glink: Move to arch_initcall()

Glink is used to communicate with the power management processor for cases
like voting for clocks and regulators.  Therefore, Glink is critical to the
boot process and should init as early as possible to unblock boot.

Move Glink from module_init() to arch_initcall() to unblock boot.
