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.

[ and so on ]
It should probably be something like
analogix_dp-objs := analogix_dp_core.o analogix_dp_reg.o
obj-$(CONFIG_DRM_ANALOGIX_DP) += analogix_dp.o
Thanks, good catch, will fix it now.
