Some edp screen do not have hpd signal, so we can't just return
failed when hpd plug in detect failed.
This is an hardware property, so we need add a devicetree property
"force-hpd" to indicate this sutiation.

But for now the connector status don't hardcode to connected,
need to operate dp phy in .detect function, so we need to revert
parts if Gustavo Padovan's changes, add phy poweron
function in bind time.

The flush work in bridge disable time is try to ensure the HPD event
won't be missed before display card disabled, actually we can take a
fast respond way(interrupt thread) to update DRM HPD event to fix the
delay update and possible dead lock.

They reason why connector need register in helper driver is rockchip drm

there would need two different connector helper functions, that's why we
leave the connector register in helper driver.

In the original split we kept the register constants intact to keep the
diff small. Still the constants are Analogix-specific, so rename them now.

Analogix dp driver is split from exynos dp driver, so we just
make an copy of exynos_dp.txt, and then simplify exynos_dp.txt
Beside update some exynos dtsi file with the latest change
