The commit 726404a66c773 ("airoha: rework RAM size handling to support
multiple RAM size") is not good enougth. It results in pacnic during
determining of memory size amount.

This patch series partly fix and partly revert the above commit.
Unfortunately for now we have no a good way to determine the an7581
memory size.
