clk: renesas: cpg-mssr: Use always-on governor for Clock Domain
As a pure Clock Domain does not have the concept of powering the domain itself, the CPG/MSTP driver does not provide power_off() and power_on() callbacks. However, the genpd core may still perform a dummy power down, causing /sys/kernel/debug/pm_genpd/pm_genpd_summary to report the domain's status being "off-0". Use the always-on governor to make sure the domain is never powered down, and always shows up as "on" in pm_genpd_summary.
