SATA: do not auto-initialize during boot
Rather than have the board code initialize SATA automatically during boot,
make the user manually run "sata init". This brings the SATA subsystem in
line with common U-Boot policy.
Rather than having a dedicated weak function "is_sata_supported", people
can override sata_initialize() to do their weird board stuff. Then they
can call the actual __sata_initialize().
