tests: flash: Fix disable_spi_nor case

This case was originally made sort of naively due to the fact that the
test was prioritizing testing spi nor first, but we wanted to test SOC
flash drivers, not the spi flash driver, so we just disabled
CONFIG_SPI_NOR. But this caused issues for platform which don't have a
storage partition or platform where the storage partition was actually
on a spi nor (because then there is no spi device leading to a linking
error with no reference to device object)

So fix by introducing a config to change the test logic to prioritize
the storage partition, which is really what we wanted to do in the first
place more directly I think.
