[PATCH 04/13] platform/chrome: cros_ec_proto: assign buffer size from protocol info

[Tzung-Bi Shih <tzungbi@kernel.org>]

`din_size` is calculated from `ec_dev->max_response`.
`ec_dev->max_response` is further calculated from the protocol info.

To make it clear, assign `din_size` and `dout_size` from protocol info
directly.
