Subject: [PATCH] clk: si5351: Simplify probe()
Date:   Sat,  9 Sep 2023 17:20:47 +0100

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.

Simplify probe() by replacing ID lookup table for retrieving match data
with i2c_get_match_data().
