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. Signed-off-by: Nikita Kiryanov <nikita@compulab.co.il> Cc: Simon Glass <sjg@chromium.org> Cc: Stefano Babic <sbabic@denx.de>
