This reverts commit 531fdbeedeb89bd32018a35c6e137765c9cc9e97.

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.

Fixes: 531fdbeedeb8 ("arm64: dts: allwinner: h6: Use RSB for AXP805 PMIC connection")
