[PATCH v5 1/7] mfd: da8xx-cfgchip: New header file for CFGCHIP registers.

We will be using a generic syscon device for the TI DA8XX SoC CFGCHIPx retisters. This will be used by a number of planned drivers including a new USB PHY driver and common clock framework drivers. The same defines are removed from the platform_data header file since they are now redundant and the
