[U-Boot] [PATCH V3] i.MX6: mx6q_sabrelite: add SATA bindings

[Eric Nelson]

Signed-off-by: Eric Nelson <eric.nelson at boundarydevices.com>

---
V2 has been stripped of the board-independent changes and
uses clrsetbits_le32() instead of twiddling bits by hand.

V3 returns immediately from setup_sata() if enable_sata_clock()
returns an error.
