[PATCH] video: fbdev: sis: Remove unnecessary parentheses and commented code

[Nathan Chancellor <natechancellor@gmail.com>]

Clang warns when multiple pairs of parentheses are used for a single
conditional statement.

drivers/video/fbdev/sis/init301.c:851:42: warning: equality comparison
with extraneous parentheses [-Wparentheses-equality]
      } else if((SiS_Pr->SiS_IF_DEF_LVDS = 1) /* ||
                 ~~~~~~~~~~~~~~~~~~~~~~~~^~~~
drivers/video/fbdev/sis/init301.c:851:42: note: remove extraneous
parentheses around the comparison to silence this warning
      } else if((SiS_Pr->SiS_IF_DEF_LVDS = 1) /* ||
                ~                        ^   ~
drivers/video/fbdev/sis/init301.c:851:42: note: use '=' to turn this
equality comparison into an assignment
      } else if((SiS_Pr->SiS_IF_DEF_LVDS = 1) /* ||
                                         ^~
                                         1 warning generated.

Remove the parentheses and while we're at it, clean up the commented
code, which has been here since the beginning of git history.
