Instead of defining two versions of intel_sysfs_rc6_init(), one for each
value of CONFIG_PM, add a check on !IS_ENABLED(CONFIG_PM) early in the
function. This will allow the compiler to automatically drop the dead
code when CONFIG_PM is disabled, without having to use #ifdef guards.
This has the advantage of always compiling these functions in,
independently of any Kconfig option. Thanks to that, bugs and other
regressions are subsequently easier to catch.
