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.
