I think above usage is correct. This will enable SPI_CADENCE_QUADSPI to
be selected when ARCH_SOCFPGA=y without having to enable COMPILE_TEST.
AFAIK, COMPILE_TEST is used usually to build test the driver w/o having
to enable ARCH specific configs (usually by maintainers).
For TI EVM, I would patch this file to add my architecture later(i.e
along with DT patch to my board).
