flashchips: Add Macronix MX25U51245G
Copy 'n paste support for Macronix MX25U51245G. I don't pretend to know
a whole lot about SPI FLASH so its mostly copied from other MX25U devices
and double checked a few bits and pieces against the datasheet.
I have tested basic probe, read, erase and write using layout files. I
tested both with 4MB@0x0000000 and 64K0@0x3f00000 (the later means I
have tested 4-byte addressing).
