mtd: spinand: winbond: Add support for W35N02JW and W35N04JW chips

These chips support single SPI, octal SPI and octal DDR SPI.

For now, only the SDR protocols are supported.

Tested with the W35N02JW variant, but the 04 one just has twice more
dies and is described in the same datasheet, so we can reasonably expect
that it will behave identically.
