hw/i2c/smbus_ich9: Include "qemu/range.h"

hw/i2c/smbus_ich9.c calls range_covers_byte(). Include "qemu/range.h"

  hw/i2c/smbus_ich9.c:66:9: error: implicit declaration of function 'range_covers_byte' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
      if (range_covers_byte(address, len, ICH9_SMB_HOSTC)) {
          ^
