The procedure of rpm_idle() is as follows.
rpm_idle
->rpm_suspend
->pm_genpd_runtime_suspend
->pm_clk_suspend
->clk_disable
->genpd_poweroff
Pm_runtime_put(dev) causes rpm_idle() to be queued up, when
pm_clk_suspend() is executed, the rockchip dmcfreq lock is
released, vop clocks may be closed while changing ddr frequency.
Use pm_runtime_put_sync() instead of pm_runtime_put(), so that
rpm_idle can be executed before the lock is released.
