Subject: [PATCH 4.9 132/145] clk: meson: gxbb: fix build error without RESET_CONTROLLER

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tobias Regnery <tobias.regnery@...il.com>

commit dbed87a9d3a857a86f602775b5845f5f6d9652b5 upstream.

With CONFIG_RESET_CONTROLLER=n we see the following link error in the
meson gxbb clk driver:

drivers/built-in.o: In function 'gxbb_aoclkc_probe':
drivers/clk/meson/gxbb-aoclk.c:161: undefined reference to 'devm_reset_controller_register'

Fix this by selecting the reset controller subsystem.

 	  Support for the clock controller on AmLogic S905 devices, aka gxbb.
 	  Say Y if you want peripherals and CPU frequency scaling to work.
