media: ix2505v: get rid of /** comments

As warned:

  drivers/media/dvb-frontends/ix2505v.c:24: warning: cannot understand function prototype: 'int ix2505v_debug; '
  drivers/media/dvb-frontends/ix2505v.c:59: warning: No description found for parameter 'state'
  drivers/media/dvb-frontends/ix2505v.c:128: warning: No description found for parameter 'fe'

None of the comments there are kernel-doc. So, remove them with:

	perl -pi -e 's,\/\*\*,/*,g' drivers/media/dvb-frontends/ix2505v.c
