bcm4908: sysupgrade: refactor handling different firmware formats
This results in setting format specific data (format info, extract commands) in a single function. It should help maintaining sysupgrade code. This change has been tested on Asus GT-AC5300 and Netgear R8000P. Signed-off-by: Rafał Miłecki <rafal@milecki.pl> (cherry picked from commit 30b168b9b8451d6165833cee75019ef7dbfd8a2e)
