[PATCH 02/11] Add more flags for sync control

[Juergen Beisert]

In order to make video mode setup and initializing a runtime job (currently
it is a compile time job) this patch tries to make the 'fb_videomode' structure
more generic. It should also carry special settings required only for some LC
displays. So, I add some additional sync flags to control the DE and CLCK to
the display (something a regular CRT does not know). Also the possibility to
stop the clock when outside active display data (required for (C)STN display).

Further suggestions for flags?

What about the special settings for some kind of Sharp displays the i.MX
processor family supports?
