[PATCH v4 0/11] Misc fixup and add RK3399 eDP support to Analogix DP driver

[Yakir Yang <ykk@rock-chips.com>]

RK3399 and RK3288 shared the same eDP IP controller, only some light
difference with VOP configure and GRF configure.

Also same misc fix to analogix_dp driver:
- Hotplug invalid which report by Dan Carpenter
- Make panel detect to an optional action
- correct the register bit define error in ANALOGIX_DP_PLL_REG_1

Changes in v4:
- Assigned the GRF setting magic numbers to a #define that corresponds to
  a TRM name. (Sean & Heiko)
- Pass the chip type to device type directly. (Sean)
- Add reviewed flag from Tomasz.
- Add reviewed flag from Sean
- Remove subdev_type number, and add 'is_rockchip(type)' helper function (Sean)
- Add reviewed flag from Tomasz.
- Improved the overly complicated .atomic_check function. (Sean)
- Add reviewed flag from Tomasz

  "dp->cgfclk"  -->  'dp->grfclk'
- Check the the error code properly, 'EPROBE_DEFER' should be returned,
  'ENOENT' should assign a NULL point to grfclk, other errors should be
  regarded as failed. (Tomasz, Doug, reviewed at Google Gerrit)
