cdx: Fix missing GENERIC_MSI_IRQ on compile test

CDX_BUS driver uses msi_setup_device_data() which is selected by
GENERIC_MSI_IRQ, thus compile testing without the latter failed:

  /usr/bin/ld: drivers/cdx/cdx.o: in function `cdx_probe':
  build/drivers/cdx/cdx.c:314: undefined reference to `msi_setup_device_data'
