video: s3c2410: fix checkpatch error and warnings

This patch fixes the checkpatch errors listed below:

ERROR: do not initialise statics to 0 or NULL
WARNING: Use #include <linux/io.h> instead of <asm/io.h>
WARNING: braces {} are not necessary for single statement blocks
WARNING: braces {} are not necessary for any arm of this statement
WARNING: static char array declaration should probably be static const char
WARNING: line over 80 characters
WARNING: msleep < 20ms can sleep for up to 20ms; see Documentation/timers/timers-howto.txt
