[PATCH v2] spi-nor: Kconfig: Improve help text for SPI_FSL_QUADSPI

[Fabio Estevam]

The current "We only connect the NOR to this controller now." text
is not very clear, so explain it better by saying that generic SPI
is not supported by SPI_FSL_QUADSPI and only SPI NOR is.

Changes since v1:
- Explain that generic SPI is not supported and only SPI NOR is as
suggested by Frank Li
