SPI RES is the most unreliable way to identify chips because it only returns a 1-byte ID for most chips. For every given ID out there, probably a dozen incompatible flash chips match it. We already refuse to identify a chip with RES if that chip responds to RDID (3 bytes, good match), and with this patch we additionally refuse RES if the chip responds to REMS (2 bytes, still a good match). This increases matching accuracy a lot.
Besides that, the RDID/REMS response checking has been cleaned up for better readability.
