stable in extrem low temperature.

The dwc3_rockchip_probe() spends lots of time to initialize
the dwc3 host and pm runtime. It significantly lengthen the
boot time.
I test on RK3399 Excavator Board, the execution time of the
dwc3_rockchip_probe() on Type-C0 is about 220ms without this
patch (Type-C0 connect to PC USB port at the same time). Most
of the time is spent on remove hcd(~16ms) and pm runtime
suspend (~180ms).
1. remove hcd (~16ms)
When do usb_remove_hcd(), the xHCI should wait 16ms to
enter the stopped state with the following log:
xhci-hcd xhci-hcd.11.auto: Host not halted after 16000 microseconds
2. pm runtime suspend (~180ms)
Race condition is observed during pm runtiem suspend.

This patch runs the remove hcd operation and pm runtime
suspend in an async_domain to speed up the boot time. With
this patch, the dwc3_rockchip_probe() spends only ~12ms.

The Seagate Expansion Portable Drive HDD (ext4 file system,
idVendor=0bc2, idProduct=2321) is reported to fail to work
on the rk3399/rk3328 platforms USB 3.0 interface with the
following error message when do read/write operation by dd
command:
xhci-hcd xhci-hcd.11.auto: Ring expansion failed
It's because that xHCI use the dma_pool_alloc() to allocate
DMA buffer for segment_pool with GFP_ATOMIC flag, however,
the default 256 KiB coherent pool is too small for the USB
HDD, so increase it to 1024 KiB to make sure that devices
will be able to allocate their DMA buffers with GFP_ATOMIC
flag.

Because uart does not have high requirements
for the clk Jitter, the fractional frequency
divider does not need to meet the 20-fold relationship.
(If uart clk rate < 24M,Use 24M as the fractional
clock source.)

The process to get current source code under midgard_for_linux/ :
1. On the status of commit 18166b65,
revert commit "91842c9 MALI: rockchip: upgrade midgard DDK to r18p0-01rel0",
which upgraded drivers/gpu/arm/midgard/ from DDK r14 to r18.
2. copy directory drivers/gpu/arm/midgard/ to drivers/gpu/arm/midgard_for_linux/.
It's ensured that changes of commits in drivers/gpu/arm/midgard/
from RK power management group early than commit 18166b65
are correspondingly remained in current drivers/gpu/arm/midgard_for_linux/.

Evb is part of a family of boards called rk3399pro. As best as possible, the
properties shared by the rk3399pro family are placed in rk3399pro.dtsi, while
Evb-linux specific bits are in rk3399pro-evb-v11-linux.dts. This does not add full
support for the base Evb board.
Working and tested (to some extent):
* cluster cpu/gpu support -- including frequency, performance
* UART / console
* Thermal
* Touchscreen
* EDP
* Wifi
* Bluetooth / Webcam
* SD card
* eMMC
* USB2/USB3
* Backlight
* DVFS: included cpu/gpu/ddr
* CAMERA: had tested the ov13850 camera
* VIDEO: tested the h264 video source
* AUDIO: play and mic music
* NPU
* HDMI
* GMAC
Not tested:
* Pcie
* MIPI
Not working:
* SD CARD: no sure, maybe the board sd card is broken by hardware.

Added this patch to support the v10 board before, as the most people used
the rk3399pro v11 board for now.
Note: this patch had *not* verified the all functions, it can bringup for
v10 board and some basic functions.
(included wifi/bt, camera, display, video, usb...and so on.)
