i2c: rename field 'alias_list' of struct i2c_atr_chan to 'alias_pairs'

The "alias_list" field of struct i2c_atr_chan describes translation table
entries programmed in the ATR channel. This terminology will become more
confusing when per-channel alias pool support is introduced, as struct
i2c_atr_chan will gain a new field called "alias_pool", which will describe
aliases which are available to the ATR channel.

Rename the "alias_list" field to "alias_pairs" to clearly distinguish it
from the future "alias_pool" field.

No functional change is intended.
