flashrom.c: Supplement `chip->unlock()` calls with wp unlocking
The full writeprotect implementation has proper support and ability to unlock flash over spi25_statusreg.c. Therefore if the required bits are available for the given chip prefer proper writeprotect support instead of adhoc spi25_statusreg.c helpers.
BUG=b:237485865 BRANCH=none TEST=Tested on grunt DUT (prog: sb600spi, flash: W25Q128.W): `flashrom --wp-range 0x0,0x1000000 \ flashrom --wp-status # Result: range=0x0,0x1000000 \ flashrom -w random.bin # Result: success \ flashrom -v random.bin # Result: success \ flashrom --wp-status # Result: range=0x0,0x1000000` TEST=Tested that chips without WP support can still be unlocked by deleting decode_range for W25Q128.W flashchip and retesting on the grunt DUT.
