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.
