flashchips: Add Macronix MX25V1635F support
See https://www.mxic.com.tw/Lists/Datasheet/Attachments/8662/MX25V1635F,%202.5V,%2016Mb,%20v1.4.pdf .
I've tested this patch with the MX25V1635F I have here, using serprog
and ftdi by (re)writing a few images to the flash and seeing if changes
were stored correctly. This also included erasing and rewriting the
memory with completely different data, so erase is tested, too.
