Split the dp core driver from exynos directory to bridge directory,

Beside the new analogix_dp driver would export six hooks.
"analogix_dp_bind()" and "analogix_dp_unbind()"
"analogix_dp_suspned()" and "analogix_dp_resume()"
"analogix_dp_detect()" and "analogix_dp_get_modes()"
The bind/unbind symbols is used for analogix platform driver to connect
with analogix_dp core driver. And the detect/get_modes is used for analogix
platform driver to init the connector.
They reason why connector need register in helper driver is rockchip drm
haven't implement the atomic API, but Exynos drm have implement it, so
there would need two different connector helper functions, that's why we
leave the connector register in helper driver.

Sorry to introduce an compiled error, my test 4.4-rc3 kernel have some
different with linux-next kernel, so i used to write the patches on next
kernel,
and back the changes to my 4.4 kernel to test.
I already found this error when I'm testing, but forget to reserver this
changes
to linux-next kernel, I would send a new version to fix this.
