cinap_lenrek 5ea540e75d sdiahci: enable pci busmaster before ahciconfigdrive() (fix qemu crash)
enable pci busmaster before set the fis-receive-enable
bit in the port command register.

not doing so triggers a crash in qemu like:

address_space_unmap: Assertion `mr != NULL' failed.

as qemu tries to process the dma command list as soon
as we set that flag and busmaster dma needs to be enabled
at this point.
