flashchips: Enable FEATURE_4BA_EAR_1716 for ISSI chips
According to their datasheets, ISSI IS25LP256 and IS25WP256 support
both 0xc5/0xc8 and 0x17/0x16 opcodes to write / read their extended
address register. Flashrom will use 0xc5 by default if available,
so adding the FEATURE_4BA_EAR_1716 flag makes no difference for now
(FEATURE_4BA_EAR_C5C8 is included in the already selected FEATURE_4BA
set). It's better to have a comprehensive description of the chips,
though, in case somebody wants to use them in the future with a
master that restricts available opcodes.
