Subject: [PATCH] clk: npcm: select CONFIG_AUXILIARY_BUS

From: Arnd Bergmann <arnd@...db.de>

There are very rare randconfig builds that turn on this driver but
don't already select CONFIG_AUXILIARY_BUS from another driver, and
this results in a build failure:

arm-linux-gnueabi-ld: drivers/clk/clk-npcm8xx.o: in function `npcm8xx_clock_driver_init':
clk-npcm8xx.c:(.init.text+0x18): undefined reference to `__auxiliary_driver_register'

Select the bus here, as all other clk drivers using it do.

Fixes: e0b255df027e ("clk: npcm8xx: add clock controller")
