Revert "arm64: dts: allwinner: h6: Use RSB for AXP805 PMIC connection"

[ Upstream commit 573f99c7 ]

This reverts commit 531fdbee.

Hardware that uses I2C wasn't designed with high speeds in mind, so
communication with PMIC via RSB can intermittently fail. Go back to I2C
as higher speed and efficiency isn't worth the trouble.
