Add FEATURE_REGISTERMAP to some more chips and change the use of various probing functions

Browse Source 
Add FEATURE_REGISTERMAP to * Intel 82802AB, 82802AC * Sharp LHF00L04 * SST SST49LF004C, SST49LF008C, SST49LF016C, SST49LF160C * ST M50FLW040A, M50FLW040B, M50FLW080A, M50FLW080B, M50FW002, M50FW016      M50FW040, M50FW080, M50LPW116.

Make register mapping conditional on FEATURE_REGISTERMAP in 82802ab.c.
Replace probe_49lfxxxc with probe_82802ab.
Replace probe_28sf040 with probe_82802ab.
Replace probe_sst_fwhub with probe_jedec.
Add printlock_sst_fwhub to chips which used probe_sst_fwhub.
