[PATCH] spi: airoha: initialize as_ctrl at pointer declaration

[Lorenzo Bianconi]

This patch introduces just two cosmetic changes to airoha spi-nand driver:
- move airoha_snand_ids definition after airoha_snand_probe routine
- always initialize airoha_snand_ctrl pointer similar to
  airoha_snand_dev one
