Since commit 4a3cc7fb6e63 ("spi: spi-mem: Introduce a capability structure")
introduced a new struct spi_controller_mem_caps to indicate the DTR mode is
supportd or not. For S32G fsl-qspi, it uses DTR mode, so set it to true to
tell that the DTR mode is enabled, or else, there will be following error:
# dmesg | grep nor
spi-nor spi6.0: Software reset failed: -524
