drm/ast: Rename struct i2c_algo_bit_data callbacks and their parameters

Align the names of the algo-bit helpers with ast's convention of
using an ast prefix plus the struct's name plus the callback's name
for such function symbols. Change the parameter names of these
helpers to 'data' and 'state', as used in the declaration of struct
i2c_algo_bit_data. No functional changes.
