The only reason R8A779 selects I2C is because they need
regulator-quirk-rcar-gen2.c. Without schematics, it's hard to say if this is
needed for SK-RZG1M, too.
The Board Hardware Manual states SK-RZG1M has both DA9063 and DA9210.
It does state DA9063 is connected to IRQ2, but doesn't mention an interrupt
line for DA9210, so we don't know if they share IRQ2. Note that the Koelsch
fails to mention that DA9210 uses IRQ2, so this doesn't mean much.
For Porter we do not have the quirk enabled, while it has both regulators, too.
You can try to enable regulator-quirk-rcar-gen2.c for "renesas,sk-rzg1m" too,
and see what's printed by the kernel after a cold boot...
