Subject: PM / devfreq: rk3399_dmc: Fix module autoload
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.

terminated
The rest of the code uses ARRAY_SIZE to count the number of entries in
ppmu_events array. The NULL terminated entry makes ARRAY_SIZE return
off-by-one value.
