pinctrl: mvebu: Fix i2c sda definition for 98DX3236

Browse Source 
Per the datasheet the i2c functions use MPP_Sel=0x1. They are documented
as using MPP_Sel=0x4 as well but mixing 0x1 and 0x4 is clearly wrong. On
the board tested 0x4 resulted in a non-functioning i2c bus so stick with
0x1 which works.
