i2c: rk3x: add i2c support for rk3399 soc

- new method to caculate i2c timings for rk3399:
  There was an timing issue about "repeated start" time at the I2C
  controller of version0, controller appears to drop SDA at .875x (7/8)
  programmed clk high. On version 1 of the controller, the rule(.875x)
  isn't enough to meet tSU;STA
  requirements on 100k's Standard-mode. To resolve this issue,
  sda_update_config, start_setup_config and stop_setup_config for I2C
  timing information are added, new rules are designed to calculate
  the timing information at new v1.
- pclk and function clk are separated at rk3399.
- support i2c highspeed mode: 1.7MHz for rk3399

UPSTREAM: drm/rockchip: don't wait for vblank if fb hasn't changed

As commented in drm_atomic_helper_wait_for_vblanks(), userspace relies
on cursor ioctls being unsynced.  Converting the rockchip driver to
atomic has significantly impacted cursor performance by making every
cursor update wait for vblank.

By skipping the vblank sync when the framebuffer has not changed (as is
done in drm_atomic_helper_wait_for_vblanks()) we can avoid this for the
common case of moving the cursor and only need to delay the cursor ioctl
when the cursor icon changes.

We cannot add the check on legacy_cursor_update since that results in
the cursor bo being unreferenced while the hardware may still be reading
it.  Fully supporting unsynced cursor updates is left for the future
when the atomic helper framework supports async updates.

not a good idea to avoid this tearing. we can avoid tearing by using
standby register.

Vop standby register will take effect at end of current frame, and
go back to work immediately when exit standby.

So we can use standby register to protect this context.

phy: rockchip-emmc: fix compile issue on arm64 platform

This patch rename "reg" property to "reg_offset".
We rename it to fix the compile issue on ARM64 platform:
(reg_format): "reg" property in /phy has invalid length (4 bytes)
(#address-cells == 2, #size-cells == 2)

This's because "reg" is very special one which should keep the
*-cells with its parent node and can't be overwrited even if we
do that explicitly. On 32-bit plafform, the default *-cells
fit for what we assign to "reg". But that's not correct for 64-bit
platform. So we can see two possible solutions to fix this problem:
A) make phy-rockchip-emmc as a child phy node and overwrite its
parent's #address-cells and #size-cells.
B) avoid using this special property.

we use it just for passing on a offset for different Socs, and there's
no requirement to change the code to make phy-rockchip-emmc as a child
node. so choose option B) is sane.

UPSTREAM: clk: rockchip: only enter pll slow-mode directly before reboots on rk3288

As commit 1d33929e2a2b ("clk: rockchip: switch PLLs to slow mode before
reboot for rk3288") states, switching the PLLs to slow-mode is only
necessary when rebooting using the soft-reset done through the CRU.

The dwc2 controllers used create really big number of interrupts in
special constellations involving usb-hubs and their number is so high,
it can even overwhelm the interrupt handler if the cpu-speed os to low.

Right now the PLLs are put into slow-mode in a shutdown syscore_ops
callback which means it happens on all reboots (not only the soft-reset
ones) and even on poweroff actions.

This can result in the system not powering off and getting stuck instead,
so we should move the slow-mode change nearer to the actual reboot action.

For this we introduce the possiblity to also set a callback that gets
called from the restart-handler directly prior to restarting the system
and move the shutdown-callback to this new option.

With this the slow-mode switch is done only on the necessary reboots
and also has a smaller possibility of causing artifacts.

UPSTREAM: clk: rockchip: switch PLLs to slow mode before reboot for rk3288

We've been seeing some crashes at reboot test on rk3288-based systems,
which boards have not reset pin connected to NPOR, they reboot by
setting 0xfdb9 to RK3288_GLB_SRST_FST register. If the APLL works in
a high frequency mode, some IPs might hang during soft reset.
It appears that we can fix the problem by switching to slow mode before
reboot, just like what we did before suspend.

    or notify the PMIC via a GPIO. This should be set in the specific board.

2) Thermal zones:
