Hauke Mehrtens 34a422794d sunxi: Backport patches needed for A64
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.

This enables support for Allwinner sunxi based SoCs like the A64.
