PM / Domains: fix redundant genpd_save_dev call in suspend_noirq

This is wrong behavior that invokes "genpd_save_dev" function in
pm_genpd_suspend_noirq, which will finally call the runtime_suspend
callback function of the device. And this is not the expected behavior of
regular suspend sequence in kernel and doesn't align with upstream
kernel.

Same as the resume_noirq flow. We should fix it. But some drivers can
not work with it, e.g. pcie, so using the same flag
GENPD_FLAG_PM_UPSTREAM to make it work with other downstream drivers.
