s3c-fb: fix distortedness situation for the mode more then 24bpp
It has been working fine at 16bpp but in case of pixel format more then
24bpp it would occur distortedness situation on that mode. so this patch
set the word swap control bit of WINCONx to 1 as default value. but it
should be set to 0 in case that each ENLOCAL bit of WINCON0 ~ 2 registers
is enabled. this issue would be solved with local path feature soon.
