sunxi: rework target

 - update kernel to 3.12
 - add patches for clocks, i2c, usb, sid, rtc
 - support common image for A10/A13/A20
 - add support for a couple boards
 - most drivers are configured into the kernel as of now

+Subject: [PATCH] clk: sunxi: add gating support to PLL1
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This commit adds gating support to PLL1 on the clock driver. This makes
+the PLL1 implementation fully compatible with PLL4 as well.
