clk: cdce925: Extend match support for OF tables

The driver has an OF match table, still, it uses an ID lookup table for
retrieving match data. Currently, the driver is working on the
assumption that an I2C device registered via OF will always match a
legacy I2C device ID. The correct approach is to have an OF device ID
table using i2c_get_match_data() if the devices are registered via OF/ID.

Unify the OF/ID table by using struct clk_cdce925_chip_info
as match data for both these tables and replace the ID lookup table for
the match data by i2c_get_match_data().

Split the array clk_cdce925_chip_info_tbl[] as individual variables, and
make lines shorter by referring to e.g. &clk_cdce913_info instead of
&clk_cdce925_chip_info_tbl[CDCE913].

Drop enum related to chip type as there is no user.

While at it, remove the trailing comma in the terminator entry for the OF
table making code robust against (theoretical) misrebases or other similar
things where the new entry goes _after_ the termination without the
compiler noticing.
