[PATCH 2/4] ARM: mach-shmobile: r8a7779: add SATA support

From: Vladimir Barinov <vladimir.barinov at cogentembedded.com>

Add SATA clock and platform device resources on r8a7779 SoC.
Add entry to r8a7779_auxdata_lookup[], so that devm_clk_get() in the driver
still works when we're using the device tree.
