flashchips: enable write-protection for W25Q{64,128}.V

Browse Source 
Configuration for W25Q64 was tested on hardware (W25Q64FV).

Emulation of W25Q128 in dummyflasher will be extended to support WP.
Haven't tested this one on hardware, but it's the same configuration as
for W25Q64 except that it has WPS.

W25Q64JV chip was renamed to W25Q64JV-.M (those with QPI).

W25Q64.V chip was split into W25Q64BV/W25Q64CV/W25Q64FV (no SR3 and WPS)
and W25Q64JV-.Q (SR3 and WPS, but no QPI).
