drivers/i2c/generic: Re-factor SSDT generation code
1. Export i2c_generic_fill_ssdt to allow other device-specific i2c drivers to share and re-use the same code for generating AML code for SSDT. In order to achieve this, following changes are required: a. Add macro I2C_GENERIC_CONFIG that defines a structure with all generic i2c device-tree properties. This macro should be placed by the using driver at the start of its config structure. b. Accept a callback function to add any device specific information to SSDT. If generic driver is used directly by a device, callback would be NULL. Other devices using a separate i2c driver can provide a callback to add any properties to SSDT. 2. Allow device to provide _CID.
