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

Browse Source 
On boards where the only peripheral connected to PL0/PL1 is an X-Powers
PMIC, configure the connection to use the RSB bus rather than the I2C
bus. Compared to the I2C controller that shares the pins, the RSB
controller allows a higher bus frequency, and it is more CPU-efficient.
