   6 The sunxi clk driver causes a link error when the reset controller
   7 subsystem is disabled:
   8
   9 drivers/clk/built-in.o: In function `sun4i_ve_clk_setup':
  10 :(.init.text+0xd040): undefined reference to `reset_controller_register'

  14 :(.init.text+0x10074): undefined reference to `reset_controller_register'

  16 We already force it to be enabled on arm32 and some other arm64 platforms,
  17 but not on arm64/sunxi. This adds the respective Kconfig statements to
  18 also select it here.
