Get the 4-Byte Address mode method from BFPT and favor it in the detriment of the "default" set_4byte_addr_mode method or the methods set by vendors. This may introduce some regressions if flashes have wrong BFPT data. The fix is to introduce post_bfpt() hooks and fix where needed. We should let the core/sfdp do the params initialization, and do vendor specific updates just where needed.
