clk: renesas: mstp: Set GENPD_FLAG_ALWAYS_ON for clock domain
[ Upstream commit a459a184c978ca9ad538aab93aafdde873953f30 ]
The CPG/MSTP Clock Domain driver does not implement the
generic_pm_domain.power_{on,off}() callbacks, as the domain itself
cannot be powered down. Hence the domain should be marked as always-on
by setting the GENPD_FLAG_ALWAYS_ON flag, to prevent the core PM Domain
code from considering it for power-off, and doing unnessary processing.
This also gets rid of a boot warning when the Clock Domain contains an
IRQ-safe device, e.g. on RZ/A1:
sh_mtu2 fcff0000.timer: PM domain cpg_clocks will not be powered off
