[nrf fromlist] tests: drivers: spi: lower nrf54l and nrf7120 SPI freq to 8MHz

The nrf7120 and nrf54l SPIM21 and SPIM22 instances do not support
16MHz, and the SPIS21 only supports up to 8MHz according to the
datasheet. The SPIS21 is the target device, which is what defines
the spi-max-frequency, compared to the max-frequency of the bus,
which does correctly set it to 8MHz for the SPIM instances.

Lower the spi-max-frequency to 8MHz, and remove the nrf7120 from
the 16Mhz and 32Mhz test case from testcase.yaml
