flashchips: add Winbond W25R512NW / W74M51NW

Browse Source 
I used W25Q256JW as a template and just increased every erase size
calculation.

Datasheet can be found by form contact only via
https://www.winbond.com/hq/product/code-storage-flash-memory/serial-nor-flash/?__locale=en_TW&partNo=W25R512NW

I tested it by running:
dd if=/dev/urandom of=/tmp/random.bin bs=1M count=64
sudo /tmp/flashrom/build/flashrom -p ft2232_spi:type=2232H -w /tmp/random.bin --progress
sudo /tmp/flashrom/build/flashrom -p ft2232_spi:type=2232H -v /tmp/random.bin
And I saw "Verifying flash... VERIFIED."
