Update devfreq next for v6.4

Browse Source 
Detailed description for this pull request:
 1. Remove unneeded SRCU selection in Kconfig because it's always set from
 devfreq core.
 
 2. Fix minor updates of devfreq drivers
 - Drop of_match_ptr macro from exynos-bus.c because this driver is always using
 the DT table for driver probe.
 - Use the preferred of_property_present instead of the low-level of_get_property
 on exynos-bus.c
 - Use devm_platform_get_and_ioream_resource on exyno-ppmu.c
