I don't think it has anything to do with USB. With the current
dependency, X-Gene SATA AHCI driver will be included if either ARM64
or COMPILE_TEST. It in turn will select "PHY_XGENE" which has
dependency on OF and HAS_IOMEM. An fix would be make AHCI_XGENE
depends on OF as suggested by Linus. This is trigger by "COMPILE_TEST"
for non-ARM64. We can also remove "COMPILE_TEST" from AHCI_XGENE
driver like other SATA drivers. My prefer solution is to remove
