Changes since v4:
- rely on devm_platform_ioremap_resource() routine
- rework airoha_snand_is_page_ops() routine
Changes since v3:
- rely on devm_kzalloc() to allocate airoha_snand_dev buffers
- rely on dev_err_probe()
- cosmetic rework
Changes since v2:
- Fix compilation warnings
- Remove interrupt entry in dts since it is not connected so far
Changes since v1:
- Introduce spi clock dependency
