Subject: [PATCH v2 1/6] cdx: Enable compile testing

There is no code limited to ARM64 or OF/Devicetree in the CDX bus
driver, so CDX_BUS can be compile tested on all platforms.
CDX_CONTROLLER on the other hand selects REMOTEPROC which depends on
HAS_DMA, so add that dependency for compile testing.
