flashchips: Test MXIC MX25U25643G wp

The MX25U25643G has a WPSEL bit in the security register, but the MX25U25635F does not.
Therefore, take them apart.

The MX25U25643G has been tested by ch341a programmer : read, write, erase and wp.

MX25U25643G datasheet is available at the following URL:
https://www.mxic.com.tw/en-us/products/NOR-Flash/Serial-NOR-Flash/Pages/spec...

MX25U25635F datasheet is available at the following URL:
https://www.macronix.com/en-us/products/NOR-Flash/Serial-NOR-Flash/Pages/spe...
