i2c: sis630: correct format strings

When compiling with -Wformat, clang warns:

drivers/i2c/busses/i2c-sis630.c:482:4: warning: format specifies type
      'unsigned short' but the argument has type 'int' [-Wformat]
                        smbus_base + SMB_STS,
                        ^~~~~~~~~~~~~~~~~~~~

                        smbus_base + SMB_STS + SIS630_SMB_IOREGION - 1);
                        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

                                          ~~~~~   ^~~~~~~~~~~~~~~~~~~~

This patch fixes the format strings to use the format type for int.
