eeprom: at25: add support for Infineon Cypress QSN FRAMs
Add support for Infineon Cypress CY15****QSN FRAM chips.
Unlike the QN variants these chips have an 8 byte JEDEC ID.
The layout of the serial number matches that of already supported chips
like the CY15B204QN, so make the read-out unconditional.
Tested with the CY15B204QSN. According to Infineon datasheets, all QSN
variants appear to share a consistent pattern so the size should be
correctly detected based on the density bits in the ID:
CY15B201QSN: 0x00 00 00 00 06 82 54 40, density_id: 8: 1Mb
CY15B102QSN: 0x00 00 00 00 06 82 51 48, density_id: 9: 2Mb
CY15B204QSN: 0x00 00 00 00 06 82 54 50, density_id: 10: 4Mb
CY15V108QSN: 0x00 00 00 00 06 82 52 58, density_id: 11: 8Mb
