superio/smsc: Restore sio1036

Browse Source 
Change d3a1a417 "src/superio: Remove unused superio chips" removed
all unused devices except for ones used on mainboards still under
review.  The SMSC 1036 was inadvertenly also removed as well.  This
device is used in debug cards that may be connected to AMD CRBs.

This patch restores the smsc1036 directory as-is and then corrects
the following lint messages.
 * WARNING: Prefer 'unsigned int' to bare use of 'unsigned'
 * ERROR: else should follow close brace '}'
 * WARNING: braces {} are not necessary for single statement blocks
