i2c: mvtwsi: Fix order of address bytes (high to low)
Patch f8a10ed1 [i2c: mvtwsi: Make address length variable] accidentally inverted the sequence of address bytes sent to the I2C device. This patch corrects this by sending the highest byte first and the lowest byte last again. Tested on theadorable Armada-XP board.
