[U-Boot] [PATCH v2 3/6] sunxi: add AXP_PMIC_BUS invisible options for AXP PMICs access

[Icenowy Zheng]

For AXP PMICs' drivers some functions are needed to provide I/O access
for the PMIC.

The source file used to be controlled by different AXPxxx_POWER config
option.

Control the file's compliation via a generic AXP_PMIC_BUS option, and
make all AXPxxx_POWER select this option, to prevent furtherly more and
more AXP PMIC names are added to the Makefile of mach-sunxi.
