spi: dt-bindings: spi-sg2044-nor: Change SOPHGO SG2042

With further testing, directly using the spi-sg2044-nor driver on SG2042
does not work. SG2042 is found to lack full compatibility with SG2044.
SG2044 has OPT register and it's necessary to write but SG2042 does not.
Due to other possible hardware detail differences, it is better
to bind SG2042 independently.
