Switch SST49LF004A/B to block erase, remove the hack which simulated (unsupported) chip erase

Browse Source 
Annotate SST49LF004B quirks for TBL#.

Add TEST_OK_PRW which is useful when a PREW chip gets a new erase
routine.

Change a few erase function prototypes to use unsigned int instead of
int.

Corresponding to flashrom svn r731.
