Ideally, the Linux kernel should get the hardware in its most
untouched state. For the most part, U-Boot does not reset the various
subsystems it touches before boot, and usually Linux deals with it, but
on some boards (cm_fx6) the Linux kernel fails to detect the ssd
correctly if sata is used by U-Boot.

Power off sata on OS boot so that Linux will have a clean state to work
with.

Implement sata stop command.
This introduces the __sata_stop() weak function, which mirrors
the weak __sata_initialize() function, giving users the option of
undoing the custom steps performed in overrides of sata_initialize().

Add reset_sata() to the sata driver interface and implement it
for dwc_ahsata. This function cleans up after sata_init(), and
therefore accepts a device number like sata_init() does.
A dummy implementation is provided for the rest of the drivers.

gw_ventana can boot from SPI or NAND and both of these interfaces boot from
the same 0x400 offset.

This means that we could simplify the code and replace the custom gw_ventana.cfg
with the generic spl_sd.cfg, as it provides the same boot offset of 0x400.
