    Add support for AMIC Technology A49LF040A and do not probe W29EE011 anymore · b9f61744

    Jens sent the first patch that added A49LF040A to flash.h and flashchips.c
    using _jedec and _49lf040 functions.
    
    An issue was found with probe_w29ee011() for the Winbond W29EE011, which
    caused the A49LF040A to no longer respond to any commands.
    
    Ward made a patch to disable probing by default for the W29EE011 following
    some discussion. Using -c W29EE011 will make flashrom probe for the chip.
    
    Peter did some more datasheet diving and found that the Pm49FL00x functions
    suited this chip quite well because of the block locking registers in
    A49LF040A, and finally tested PROBE READ ERASE WRITE to work on ALIX.3c3.
    
    Ward confirmed that this works on alix.2c3 too.
    
    Corresponding to flashrom svn r260 and coreboot v2 svn r3368.
