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.
