[PATCH 3/5] ARM: imx: imx53: Add SATA PHY clock

[Marek Vasut]

Add SATA PHY clock which are derived from the USB PHY1 clock. Note that this
patch derives the SATA PHY clock from USB PHY1 clock gate so that the SATA
driver can ungate both the SATA PHY clock and USB PHY1 clock for the SATA to
work correctly.
