Tony Xie 63ebf051b0 rockchip: fix the scu idle for rk3399
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.

Caesar Wang 9d5aee2b1f 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.

Caesar Wang 0786d68853 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)

Caesar Wang 1760db680d rockchip: support plat SIP runtime service
Software executing in the normal world and in the trusted world at
exception levels lower than EL3 will request runtime services using the
SMC instruction.

See the documentation here:

rt-svc-writers-guide.md

This to be implemented as an EL3 Runtime Service in rockchip BL31
platform port, using the "SiP Service Call" range as specified in the
SMC Calling Convention.
This doesn't support any SMC yet, we will support it in later.

Sandrine Bailleux ed81f3ebbf Introduce utils.h header file
This patch introduces a new header file: include/lib/utils.h.
Its purpose is to provide generic macros and helper functions that
are independent of any BL image, architecture, platform and even
not specific to Trusted Firmware.

For now, it contains only 2 macros: ARRAY_SIZE() and
IS_POWER_OF_TWO(). These were previously defined in bl_common.h and
xlat_tables.c respectively.

bl_common.h includes utils.h to retain compatibility for platforms
that relied on bl_common.h for the ARRAY_SIZE() macro. Upstream
platform ports that use this macro have been updated to include
utils.h.

link list. During bl31 setup time, we travse the list to process each

parameter, and do hardware control in BL31. This structure also can
pass other parameter to BL31 in future.

This patch has the following change for rk3399.

* Set the uart to 115200 since the loader decide to set
  uart baud to 115200Hz. So the ATF also should set uart baud to 115200.

* We need ensure the bl31 base is greater than 4KB since there are have
  the shared mem for coreboot.(Note: the previous vesion was tested with uboot)
