    There are two ways to opportunistically increment a device's runtime PM
    usage count, calling either pm_runtime_get_if_active() or
    pm_runtime_get_if_in_use(). The former has an argument to tell whether to
    ignore the usage count or not, and the latter simply calls the former with
    ign_usage_count set to false. The other users that want to ignore the
    usage_count will have to explicitly set that argument to true which is a
    bit cumbersome.

    To make this function more practical to use, remove the ign_usage_count
    argument from the function. The main implementation is in a static
    function called pm_runtime_get_conditional() and implementations of
    pm_runtime_get_if_active() and pm_runtime_get_if_in_use() are moved to
    runtime.c.
