[PATCH v5 0/3] i2c: spacemit: improve clock handling and cleanups

[Troy Mitchell]

This patch series contains a set of small improvements and cleanups for
the SpacemiT I2C controller driver.

The main change in this series is to improve SCL frequency accuracy by
configuring the ILCR register based on the requested clock rate, rather
than relying on the hardware reset defaults.

The ILCR is exposed as a managed clock via the Common Clock Framework,
allowing the driver to program appropriate divider values for standard
and fast modes.

In addition, the series removes a spurious warning when the optional
clock-frequency DT property is absent, and performs minor whitespace
cleanup in the driver source.
