mtd: spi-nor: cadence-quadspi: Add support for Octal SPI controller Cadence OSPI controller IP supports Octal IO (x8 IO lines), It also has an integrated PHY. IP register layout is very similar to existing QSPI IP except for additional bits to support Octal and Octal DDR mode. Therefore, extend current driver to support Octal mode. Only Octal SDR read (1-1-8)mode is supported for now. Tested with mt35xu512aba Octal flash on TI's AM654 EVM.
