FS#1087 - LEDE snaphost: sunxi cortex-a7, BanaPi target: USB not powered
User who did this - Antonio (Menion)

----------
Problem found
The new AXP20X driver is now separated by the connection bus
So for bananapi (and other board, if not all...) it is required to set to yes CONFIG_MFD_AXP20X_I2C which is not in the current config-4.9
