Change the default behaviour of the flash partition choice when no matching compatible is found. The new default is the grandparent node of the fixed-partition. As the grandparent node is what the jedec_spi_nor and nordic_qspi_nor compatibles were selecting, remove these as separate checks. This allows the flash_map API to be used for implementations of the flash API other than the 3 originally specified (soc_nv_flash, jedec_spi_nor & nordic_qspi_nor). Fixes #26397 Signed-off-by: Jordan Yates <jordan.yates@data61.csiro.au>
