This patch do following things:
1. Request hresetn_cm0s_pmu_req first then request
poresetn_cm0s_pmu_req during M0 enable.
2. Do not diable M0 clock for ddr dvfs.
3. Correct the clk_pmum0_gating_dis bit, it is BIT0 not BIT1
4. do not set/clear hclk_noc_pmu_en in M0 code, it does not relate
to the M0 clock.

rockchip: rk3399: add support for ddrfreq suspend/resume
...
This patch sets the frequency configuration of the next DRAM DFS index
to the configuration of the current index. This does not perform a
frequency transition. It just configures registers so the training on
resume for both indices will be correct.

rockchip: disable watchdog during suspend
...
The CA53 and CM0 WDT clock gating in rk3399 SGRF, and ATF is in charge of
it because the kernel can't touch SGRF.
Basically the WDT didn't stop at suspend time, it just switched from the
24M to the 32k clock. That meant that the WDT would fire if you slept for
long enough. In other word, the watchdog timer over count will increase to
750 (24*1000/32) times.
The RK3399 HW watchdog interval is 21 seconds. When machine enters the
suspend, the watchdog will reset the system after 35.7 (750/21) hours.
BUG=chrome-os-partner:59257
TEST=daisydog checked and set value, powerd_dbus_suspend to verify.

rockchip: clear the power mode status via M0
...
Due to the PMU design, the PMU may not clear the WAKEUP bit after
wakeup, therefore, the state machine at the power mode may enter
the infinite loop during WFI.
There is a solution that we can use the M0 to monitor the WAKEUP
bit and clear it during power mode, then the state machine will be
recovered immediately. Then, the DUT can exit the WFI normally.

Therefore, we can remove the unused codes which copying explicitly

As rk3399 reported the d8/octane scores drop 10% with cpu idle.
The root cause is thc cpu cluster enter the slow mode.
We don't need switch the clock to 24MHz if cpu cluster enter the
retention mode. In order to improve performance, it just needs for
cluster enter powering off mode.
Also, we shouldn't do anything for hlvl if the system is off.

rockchip: on rk3399 enable Schmitt trigger on 32 kHz clock
...
If we don't enable the Schmitt trigger on the 32 kHz clock then systems
won't always resume from suspend properly. Presumably anything else in
the system that relies on the 32 kHz clock also will have problems
without the Schmitt trigger enabled.
Enable it always since having the 32 kHz clock on GPIO0_A0 isn't
exactly an optional feature, so all boards using rk3399 will need this.

rockchip: on rk3399 init the PMU counts at boot; set 24M/32k properly
...
In a previous change we mistakenly thought that PMU_24M_EN_CFG directly
controlled whether the PMU counts ran off the 32k vs. 24M clock.
Apparently that's not true. Real logic is now documented in code.
Also in the previous change we mistaknely though that PMU_24M_EN_CFG was
normally supposed to be 1 and we should "restore" it at resume time.
This is a terrible idea and made the system totally unreliable after
resume. Apparently PMU_24M_EN_CFG should always be 0 with all the
current code and settings.
Let's fix the above two problems. While we're changing all of this,
let's also:
1. Init at boot time. Many of these counts are used when the system is
running normally. We want the behavior at boot to match the behavior
after suspend/resume.
2. Init CPU counts to be 1 us. Although old code was trying to set this
to 1 ms (1000x slower) at suspend/resume time, we've been testing the
kernel with 1 us for a long time now. That's because the kernel (at
boot time) set these values to 24. Let's keep at 24 until we know
that's wrong.
3. Init GPU counts to be 1 us. Old code wasn't touching the GPU, but as
documented in comments it makes sense to init here. Do it.
4. Document the crap out of this code, since the SoC's behavior is
confusing and poorly documented in the TRM.
5. Increase some stabilization times to 30 ms (from 3 ms). It's unclear
that a full 30 ms is needed, but let's be safe for now.
This also inits the counts for the GPU.
(Thanks to Doug's patch that come from https://crosreview.com/372381)
