Some rk3399 GRF (Generic Register Files) definitions can be used for
different drivers. Move these definitions to a common include so we
don't need to duplicate these definitions.

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.
Export the module alias information using the MODULE_DEVICE_TABLE() macro.

$ modinfo drivers/devfreq/event/exynos-ppmu.ko | grep alias

for_each_child_of_node() performs an of_node_put() on each iteration, so
putting an of_node_put() before a continue results in a double put.

The Kconfig currently controlling compilation of this code is:
config DEVFREQ_EVENT_EXYNOS_PPMU
bool "EXYNOS PPMU (Platform Performance Monitoring Unit) DEVFREQ event 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.
