Add support for w25q512jv. This is of the same series chip with
w25q256jv, which is already supported, but with size doubled and
different JEDEC ID.

We should name it "w25q512jvq" in order to differentiate it to the
"M" version: https://www.winbond.com/resource-files/W25Q512JV%20DTR%20RevD%2006292020%20133.pdf
The flash supports BP locking and we can enable it if you can test
the locking with mtd-utils. Not mandatory though.
Cheers,

I tried flash lock on my test enviorment, but it doesn't work. I think I'll
only update the flash name in next version, and submit a new patch when I
have answer to it.
Best,

Add support for w25q512jvq. This is of the same series chip with
w25q256jv, which is already supported, but with size doubled and
different JEDEC ID.
Tested on Intel whitley platform with dd from/to the flash for
read/write respectly, and flash_erase for erasing the flash.
