rockchip: syscon: Update to work with of-platdata

Browse Source 
The syscon devices all end up having diffent driver names with of-platdata,
since the driver name comes from the first string in the compatible list.
Add separate device declarations for each one, and add a bind method to set
up driver_data correctly.
