Subject: [PATCH v5 3/3] i2c: spacemit: drop warning when clock-frequency
 property is absent

The clock-frequency property is optional according to the DT binding.
Do not emit a warning when the property is missing and fall back to the
default frequency instead.

Fixes: 5ea558473fa31 ("i2c: spacemit: add support for SpacemiT K1 SoC")
