GPIO: MIPS: lantiq: fix overflow inside stp-xway driver

The driver was using a 16 bit field for storing the shadow value of the shift
register cascade. This resulted in only the first 2 shift registeres receiving
the correct data. The third shift register would always receive 0x00.

Fix this by using a 32bit field for the shadow value.
