fb: add s3c-fb driver for newer Samsung SoC framebuffer devices 



Add support for the newer Samsung devices, such as found in the S3C2443,
S3C6400 or S3C6410 series SoC.

It currently does not support all the alpha- or chroma-key options but it
will support more exporting more than one framebuffer ready for adding
overlay and blending functions.

	  Frame buffer driver for the built-in FB controller in the Samsung

	  SoC line from the S3C2443 onwards, including the S3C2416, S3C2450,

	  and the S3C64XX series such as the S3C6400 and S3C6410.



	  These chips all have the same basic framebuffer design with the

	  actual capabilities depending on the chip. For instance the S3C6400

	  and S3C6410 support 4 hardware windows whereas the S3C24XX series

	  currently only have two.



	  Currently the support is only for the S3C6400 and S3C6410 SoCs.
