Addressed a comment from Jingoo Han. Also added post_disable
control to exynos_dp driver.
drivers/gpu
Register exynos_dp_panel before the list of exynos crtcs and
connectors are probed.
This is needed because exynos_dp_panel should be registered to
the drm_panel list via panel-exynos-dp probe, i.e much before
exynos_dp_bind calls of_drm_find_panel().

Added routine for post_disable, removed few unwanted headers.
Refactored a lot of code
e can easily map the above scenario as shown below:
poweron LCD unit/LCD_EN = "pre_enable" callback
poweron LED unit/BL_EN = "enable" callback
poweroff LED unit/BL_EN = "disable" callback
poweroff LCD unit/LCD_EN = "post_disable" call
used for hotplug detection.
The GPIO is then set up as an edge-triggered interrupt where the
rising edge indicates hotplug-in and the falling edge indicates hotplug-out.
