regulator: mt6359: const-ify regulator descriptions

Browse Source 
The regulator descriptions and extended descriptions don't change at
runtime. The only reason they are not const is that the regulator
driver data is non-const.

Const-ify the descriptions and all references to them. For the driver
data, explicitly cast it to non-const void *.
