Revamp the warning of failing to set BIOS write enable in enable_flash_ich
- introduce a new variable 'wanted' that is used instead of 'new'
- use 'new' for the actual value contained in BIOS_CNTL after we tried to write it
- rephrase the warning which now also includes the old and new values besides the wanted one
Corresponding to flashrom svn r1435.
