This backports multiple patches from kernel 4.10 which are adding
missing support for the A64 and the pine64 board. These are the device
tree files, the pinctlk and the clock driver.

+Subject: arm64: sunxi: always enable reset controller
+
+The sunxi clk driver causes a link error when the reset controller
+subsystem is disabled:
+
+drivers/clk/built-in.o: In function `sun4i_ve_clk_setup':
+:(.init.text+0xd040): undefined reference to `reset_controller_register'
+drivers/clk/built-in.o: In function `sun4i_a10_display_init':
+:(.init.text+0xe5e0): undefined reference to `reset_controller_register'
+drivers/clk/built-in.o: In function `sunxi_usb_clk_setup':
+:(.init.text+0x10074): undefined reference to `reset_controller_register'
+
+We already force it to be enabled on arm32 and some other arm64 platforms,
+but not on arm64/sunxi. This adds the respective Kconfig statements to
+also select it here.
