Pinephone I2C Device reading via i2cdetect -y 3 very slow

Describe your issue

Attempting to use the Pinephone's pogopin I2C via i2cdetect -y 3 takes about a second or 2 for each slot.

In Mobian, this same command is instant.

What's the expected behaviour?

The operation should be alot faster and actually work.

What's the current behaviour?

In PmOS afaict I2C pogopins access is broken. This is likely a driver issue / something wrong with DTSIs / kernel config.

How to reproduce your issue?

apk add i2c-tools i2cdetect -y 3

What device are you using?

Pinephone 1.2 & 1.1
