mtd: spinand: Use more specific naming for the (quad output) read from cache ops
SPI operations have been initially described through macros implicitly
implying the use of a single SPI SDR bus. Macros for supporting dual and
quad I/O transfers have been added on top, generally inspired by vendor
naming, followed by DTR operations. Soon we might see octal
and even octal DTR operations as well (including the opcode byte).
Let's clarify what the macro really mean by describing the expected bus
topology in the (quad output) read from cache macro names.
