flashchips: Add Macronix MX25V4035F support
See https://www.macronix.com/Lists/Datasheet/Attachments/8670/MX25V4035F,%202.5V,%204Mb,%20v1.2.pdf .
I've only tested this patch with the MX25V1635F I have here, though
other chips in the series exist as well. Tested using serprog and ftdi
by writing a few images to the flash and seeing if changes were stored
correctly.
