tests: zephyr: drivers: spi: nrf54l only supports up to 8MHz SPIM

The nrf54l series SoCs only support up to 8MHz SPIM, though the
spi_controller_peripheral sets the SPIM frequency to 16MHz. This
now fails since nrfx checks if the applied frequency is valid.

Update the spi_controller_peripheral tests to set the SPIM freq to
8MHz.
