6.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Haibo Chen <haibo.chen@xxxxxxx>
commit 9228956a620553d7fd17f703a37a26c91e4d92ab upstream.
The flexspi on imx8ulp only has 16 LUTs, different with others which
have up to 32 LUTs.
Add a separate compatible string and nxp_fspi_devtype_data to support
flexspi on imx8ulp.
Fixes: ef89fd56bdfc ("arm64: dts: imx8ulp: add flexspi node")
