i2c: move ATR alias pool to a separate struct

Each I2C address translator (ATR) has a pool of client aliases which can be
used as translation targets. Some ATRs have a single alias pool shared by
all downstream channels, while others have a separate alias pool for each
channel. Currently, this alias pool is represented by the "aliases",
"num_aliases", and "use_mask" fields of struct i2c_atr.

In preparation for adding per-channel alias pool support, move the
"aliases", "num_aliases", "use_mask" and associated lock to a new struct
called "struct alias_pool".
