Toshiba was the only device manufacturer with the most accomplished phy team to come up with a small UFS1.0 device. Alas, there were no commercial platforms it can be paired with. Even UFS2.0 that was published in 2013, didn't really make it to the market: too moot to take effect. It's not until UFS2.1 that was published in 2016, were a myriad of devices and platforms flooded the market. Designated to mobile devices, dictates a rapid short lives for those platforms. Hence, we can safely remove those pre-UFS2.1 pieces of code.
