[PATCH v2 0/8] Add Analogix Core Display Port Driver

Hi all,
   The Samsung Exynos eDP controller and Rockchip RK3288 eDP controller
share the same IP, so a lot of parts can be re-used. I split the common
code into bridge directory, then rk3288 and exynos only need to keep
some platform code. Cause I can't find the exact IP name of exynos dp
controller, so I decide to name dp core driver with "analogix" which I
find in rk3288 eDP TRM ;)

Beyond that, there are three light registers setting differents bewteen
exynos and rk3288.
1. RK3288 have five special pll resigters which not indicata in exynos
   dp controller.
2. The address of DP_PHY_PD(dp phy power manager register) are different
   between rk3288 and exynos.
3. Rk3288 and exynos have different setting with AUX_HW_RETRY_CTL(dp debug

My series patches can be divider into two parts: One for spliting the
analogix_dp code from exynos dp driver. Another are trying to add rk3288
platform special code.

Changes in v2:
- Take Joe Preches advise, improved commit message more readable, and
  avoid using some uncommon style like bellow:
  -  retval = exynos_dp_read_bytes_from_i2c(...
  +  retval =
  +  exynos_dp_read_bytes_from_i2c(......);
- Take Jingoo Han suggest, cause I jsut improve parts
  of the code, so just remove my name from author list.
- Take Jingoo Han suggest, remove new copyright
- Fix compiled failed dut to analogix_dp_device misspell
- Add GNU license v2 declared and samsung copyright
- Fix compile failed dut to phy_pd_addr variable misspell error
