[PATCH v6 2/2] i2c: spacemit: drop warning when clock-frequency property is absent

[Troy Mitchell]

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.

Changelog in v6:
- drop Fixes tag per maintainer feedback (this is not a bug fix)
- change dev_warn to dev_info when clock-frequency is absent (it is optional)
- Link to v5: https://lore.kernel.org/r/20251226-k1-i2c-ilcr-v5-0-b5807b7dd0e6@linux.spacemit.com
