+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.
