media: s2255: Fix block comment style to kernel format

Browse Source 
Fix all 'WARNING: Block comments use * on subsequent lines' and
'WARNING: Block comments use a trailing */ on a separate line'
issues reported by checkpatch.pl in s2255drv.c. Convert block
comments to kernel-style format with leading '*' on continuation
lines and '*/' on its own line. Convert banner-style separator
comments to single-line format.
