[PATCH 6/6] ARM: sun8i: a83t: Enable AC100 codec / RTC combo chip in AXP813 PMIC

The AXP813/AXP818 PMICs used with the A83T/H8 SoCs are actually 2 dies
in one package sharing the serial bus (I2C/RSB) pins. One die is the
actual PMIC. The other is an AC100 codec / RTC combo chip.

This patch enables the RSB controller and adds the device nodes for
the AC100 chip under it.
