PM / devfreq: make exynos-bus ARM_EXYNOS_BUS_DEVFREQ tristate
The Kconfig currently controlling compilation of this code is:
devfreq/Kconfig:config ARM_EXYNOS_BUS_DEVFREQ
devfreq/Kconfig: bool "ARM EXYNOS Generic Memory Bus DEVFREQ Driver"
...meaning that it currently is not being built as a module by anyone.
Rather than rip out the existing modular code, Chanwoo indicated
that he'd rather see the driver offered as tristate.
I don't have the hardware for runtime validation, so this change
is only validated for compile and modpost.
