[PATCH 1/1] arm64: dts: imx93: Add FlexSPI support

Add FlexSPI node for i.MX93.

This is mainly taken from the downstream kernel with the clock order
fixed and 'nxp,imx93-fspi' compatible removed.
I do not know if it makes sense to add an imx93 specific compatible or
not. imx8mn uses imx8mm only, but imx8mp has it's own. But the latter
uses the same device data in the driver.
