misc: Allow kernel to be compiled with SEC_DEBUG disabled

* Guards of sec_debug.h include removed in those files that call
  functions declared in that header. The header defines empty
  functions when CONFIG_SEC_DEBUG is not defined.
* Expose extern declaration of sec_class in qpnp-power-on.c when
  CONFIG_SEC_DEBUG is not defined.
* Guard debug level sysfs tuneables.
