I am not sure if we can remove sii164. Sil164 has two configuration
method. One is from i2c R/W and the other is hardware gpio setting.

Generally, we use hardware GPIO setting. So we don't need any driver for
sil164. And that is why you see it is unused here.

But SM750LE will always require swi2c for its dvi chip. And SM750LE is a
special version of the hardware which only Huawei uses.

And if i remember correctly sii164 code will be used if USE_DVICHIP and
USE_HW_I2C are not defined.

TODO file lists removal of USE_HW_I2C and USE_DVICHIP as at that time I
planned to remove support of SM750LE but Greg suggested to keep it
(https://lkml.org/lkml/2015/3/19/353).
