Jean Delvare e296fb7f30 i2c/tsl2550: Speed up initialization 
There's some redundancy in the tsl2550 initialization sequence. It is
powering up the device twice, and setting the operating mode twice
too. Setting things just once saves SMBus transactions, which aren't
always cheap, speeding up the device initialization.
