drivers: spi: set 'spi_driver_api' as 'static const'

Browse source 
This change marks each instance of the 'spi_driver_api' as 'static const'.
The rationale is that 'spi_driver_api' is used for declaring internal
module interfaces and is not intended to be modified at runtime.
By using 'static const', we ensure immutability, leading to usage of only
.rodata and a reduction in the .data area.
