Use vendor prefixes for Kconfig symbols and filenames. This should make it easier to identify the various bridge drivers and to organize the directory.

While at it, rename dw_hdmi.[ch] to dw-hdmi.[ch] for consistency.

The likelihood of getting a large number of panel drivers from different vendors is quite high. Add a prefix to the two existing Samsung panel drivers to set a guideline for future patch submissions. Using vendor prefixes consistently should allow a cleaner organization of the tree.

Put the Kconfig entries for bridge drivers into a separate menu so that they are automatically grouped and don't clutter up the top-level menu.

While at it, move the bridge menu towards the end of the top-level menu where the panel menu is already located.
