SATA: do not auto-initialize during boot

Browse Source 
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().
