Drivers that enable runtime PM must make sure that the controller is
runtime resumed before accessing its registers to prevent the power
domain from being disabled.

Per Stephen, clk providers need to include clk-provider.h, so include in
this driver as well

Use two new helpers instead of pm_runtime_enable() and pm_clk_create(),
removing the need for calling pm_runtime_disable and pm_clk_destroy().

Add support for the Q6SSTOP clock control used on qcs404
based devices. This would allow wcss remoteproc driver to
control the required WCSS Q6SSTOP clock/reset controls to
bring the subsystem out of reset and shutdown the WCSS Q6DSP.
