PM / devfreq: passive: Fix get_target_freq when not using required-opp
The 86ad9a24f21e ("PM / devfreq: Add required OPPs support to passive governor") supported the required-opp property for using devfreq passive governor. But, 86ad9a24f21e has caused the problem on use-case when required-opp is not used such as exynos-bus.c devfreq driver. So that fix the get_target_freq of passive governor for supporting the case of when required-opp is not used. Fixes: 86ad9a24f21e ("PM / devfreq: Add required OPPs support to passive governor") Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>
