Fixes MCBIST read bug in i2c mode
I2c reads are 32 bits. This means to read an IBM logic register, the register must be read 2x, once for the left half and once for the right half of the register. This causes the read buffer to auto-increment 2x per read instead of 1x per read. As such, we have disabled the auto-increment feature in explorer for all MCBISt tests.
