iio: light: vcnl4035: fixed chip ID check

VCNL4035 register(0xE) ID_L and ID_M define as:

 ID_L: 0x80
 ID_H: 7:6 (0:0)
       5:4 (0:0) slave address = 0x60 (7-bit)
           (0:1) slave address = 0x51 (7-bit)
           (1:0) slave address = 0x40 (7-bit)
           (1:0) slave address = 0x41 (7-bit)
       3:0 Version code default	(0:0:0:0)

So just check ID_L.
