flashchips: Revise all 4BA chips
Advertise all 4BA features that are currently supported by flashrom,
plus add a new feature flag for the 4BA fast-read instruction. Also,
list all supported 3BA and 4BA erase-block functions.
As this adds a lot of new code paths that could be taken for these
chips, mark them all as untested again.
