Motivation here is to improve debug prints and while doing so to remove
some duplication and separate timing parameter validation from actual
register writes as this parameter validation and/or calculation is
needed to do only during probe.
Currently debug code prints SCL timing parameters whenever HW is
reinitialized but doesn't print importand SDA hold time nor actual bus
speed the controller is going to operate.

i2c: designware: Separate timing parameter setting from HW
initalization
i2c: designware: Add debug print for SDA hold time value
i2c: designware: Add debug print for bus speed
