Add support for winbond W25Q512NW-IM chip.
Below are the tests done:
1. Verified flashing binary image on spi card using flashrom tool.
2. Verified OTP support, below are the test results:

3. Tested flash lock, below are the test results (looks like the lock is
not working as expected, so when we do lock the whole card and tried to
write, write was successful without any errors.)

What should we do with this then? Drop the locking support? Or is there
something wrong/missing in SPI NOR core that needs to be fixed first so
locking for this flash works?

If the locking isn't working for this flash, please drop the locking flags
until you identify the problem and fix it.
