UPSTREAM: PM / devfreq: rk3399_dmc: Fix module autoload

Browse Source 
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.

Before this patch:

$ modinfo drivers/devfreq/rk3399_dmc.ko | grep alias
$

After this patch:

$ modinfo drivers/devfreq/rk3399_dmc.ko | grep alias
alias:          of:N*T*Crockchip,rk3399-dmcC*
alias:          of:N*T*Crockchip,rk3399-dmc
