The LCDC fb_info structure is only used to retrieve the default video

Instead of accessing the LCDC channel and fb_info structures directly,
use the LCDC notification callback to inform the LCDC driver about
display-related events.
Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
The callback implements 3 notification events:
- SH_MOBILE_LCDC_EVENT_DISPLAY_CONNECT notifies the LCDC that the
display has been connected
- SH_MOBILE_LCDC_EVENT_DISPLAY_DISCONNECT notifies the LCDC that the
display has been disconnected
- SH_MOBILE_LCDC_EVENT_DISPLAY_MODE notifies that LCDC that a display
mode has been detected

This patch adds s3c_fb_driverdata s3c_fb_data_exynos5 for EXYNOS5
and adds extended timing control setting.
EXYNOS5 FIMD needs extended setting for video timing control.
Additional bits are added to VIDTCON2, VIDWxxADD2, VIDOSDxA and
VIDOSDxB registers in order to set timing value for lager resolution.
Also, address offset of VIDTCONx registers is changed from 0x0
to 0x20000, thus variable type should be changed to int type
to handle the address offset of VIDTCONx registers for EXYNOS5 FIMD.

Some user scenarios need to prioritize performance over
maxiumum resolution.
Also, some devices may have bad vendor descriptors, and
this allows the user to set a pixel limit that matches
their specific device to avoid blank screens on higher

The driver was not using le16_to_cpu when reading keys from the vendor
descriptor, causing incorrect parsing. Mainly, sku_pixel_limit was not
being parsed on big-endian systems. This would result in a blank screen
on big-endian CPUs where the DL chips's max mode was smaller than the
monitor's native mode.
