Add support for cdn DP controller which is embedded in the rk3399
SoCs. The DP is compliant with DisplayPort Specification,
Version 1.3, This IP is compatible with the rockchip type-c PHY IP.
There is a uCPU in DP controller, it need a firmware to work,
please put the firmware file to /lib/firmware/rockchip/dptx.bin. The
uCPU in charge of aux communication and link training, the host use
mailbox to communicate with the ucpu.
The dclk pin_pol of vop must not be invert for DP.

This pull request contains the following rockchip drm changes:
- Introduce support for rk3399 vop/crtc
- Add PSR framework to the rockchip driver
- Implement PSR in the rockchip analogix edp driver
- Fix panel on/off in analogix to avoid damaging panels
- Some miscellaneous fixes to clean up logs and code readability

drm/rockchip: vop: introduce VOP_REG_MASK
drm/rockchip: sort registers define by chip's number
VOP have integrated a hardware counter which indicate the exact display
line that vop is scanning. And if we're interested in a specific line,
we can set the line number to vop line_flag register, and then vop would
generate a line_flag interrupt for it.
For example eDP PSR function is interested in the vertical blanking
period, then driver could set the line number to zero.
This patch have exported a symbol that allow other driver to listen the
line flag event with given timeout limit:
- rockchip_drm_wait_line_flag()

There are two VOP in rk3399 chip, respectively VOP_BIG and VOP_LIT.
most registers layout of this two vop is same, their framework are both
VOP_FULL, the Major differences of this two is that:
VOP_BIG max output resolution is 4096x2160.
VOP_LIT max output resolution is 2560x1600
VOP_BIG support four windows.
VOP_LIT only support two windows.
RK3399 vop register layout is similar with rk3288, so some feature
can reuse with rk3288.

RK3036 registers layout is quite difference with rk3288 layout,
The IC design with different framework, rk3036 vop is VOP LITE,
and rk3288 is VOP FULL.
RK3036 support two overlay plane and one hwc plane, max output
resolution is 1080p. it support IOMMU, and its IOMMU same as
rk3288's.

There are two version scale control register found on vop,
scale full version found on rk3288, support extension registers.
and scale little version found on rk3036, only support common scale.
