Subject: [PATCH v2] PM / devfreq: rk3399_dmc: Add COMPILE_TEST and
 HAVE_ARM_SMCCC dependency

To build test, add COMPILE_TEST depedency to both ARM_RK3399_DMC_DEVFREQ
and DEVFREQ_EVENT_ROCKCHIP_DFI configuration. And ARM_RK3399_DMC_DEVFREQ
used the SMCCC interface so that add HAVE_ARM_SMCCC dependency to prevent
the build break.

Reported-by: kbuild test robot <lkp@...el.com>
Signed-off-by: Chanwoo Choi <cw00.choi@...sung.com>
---
Changes from v1:
- Add HAVE_ARM_SMCCC dependency because this driver used SMCCC interface.
  It was reportd from kbuild test robot.
