[PATCH 3/3] spi: spi-sn-f-ospi: Make read-only array `width_available` static const

[Lars-Peter Clausen <lars@xxxxxxxxxx>]

The `width_available` array is currently placed on the
`f_ospi_supports_op_width()` function's stack.

But the array is never modified. Make it `static const`. This makes the
code slightly smaller and more efficient.
