mtd: spinand: Add support for read DTR operations

Advanced SPI-NAND chips are capable of reading data much faster by
leveraging DTR support. This support extends to dual and quad
configurations.

Create macros defining all possible read from cache DTR variants:
- SPINAND_PAGE_READ_FROM_CACHE_DTR_OP
- SPINAND_PAGE_READ_FROM_CACHE_X2_DTR_OP
- SPINAND_PAGE_READ_FROM_CACHE_X4_DTR_OP
- SPINAND_PAGE_READ_FROM_CACHE_DUALIO_DTR_OP
- SPINAND_PAGE_READ_FROM_CACHE_QUADIO_DTR_OP
