[PATCH] clk: rockchip: make it compile again

The RK3399 support is incomplete and we don't select CONFIG_ARCH_RK3399
from any configs and the code experienced bitrot in return.

Fix the compile error to make the driver compile again.

I know I dropped the ball here, but I got a proper setup now and intend
to rework my patches for upstreaming again soon-ish.
