Subject: [PATCH] add dual bank flash configuration info to chipid database.

add a 'has_dual_bank' info to flash param, helping handling a couple of cases
 - selecting over dual bank specific code path without handling multiple chip id all over the code.
 - handling dual bank mode dynamic configuration
