[sw] Add spi_host_tx_rx_test
Add a basic spi host tx rx test.
This test uses the spi_agent's native "loopback" behavior.
The spi agent, when in device mode, by default just plays
back whatever data is sent to it by the host.
The test prepares a random payload, sends it to the device agent,
and just reads back to make sure the data is matched.
This test DOES NOT do any kind of flash protocol checking.
- Add a device value for high speed peripehral clock
- Add a minor fix for dif_spi_host clock divider setting
