i2c: riic: Use dev_err_probe in probe and riic_init_hw functions

Refactor error handling in the riic_i2c_probe() and riic_init_hw()
functions by replacing multiple dev_err() calls with dev_err_probe().

Additionally, update the riic_init_hw() function to use a local `dev`
pointer instead of `riic->adapter.dev` for dev_err_probe(), as the I2C
adapter is not initialized at this stage. Drop the cast to (unsigned long)
in the riic_init_hw() function when printing the bus frequency, and update
the error message to display the frequency in Hz, improving clarity.
