test: dm: spi: Add testcase for spi_claim_bus()
Add testcase for spi_claim_bus(), which checks that sandbox spi bus
speed/mode settings are updated correctly when multiple slaves use
the bus consecutively. The following configurations are used for the
two spi slaves involved:
* different max_hz / different modes
* different max_hz / same modes
* different modes / same max_hz
asm/test.h header is added in order to be able to retrieve the current
speed/mode of the sandbox spi bus, via sandbox_spi_get_{speed, mode}.
