spi: spi-sn-f-ospi: Make read-only array width_available static const

Browse Source 
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.
