The code for this was already present as it seems to behave the same as the Video, but CONFIG_CHARGING had not been set, probably for lack of testing. It has now been tested.
This allows the WPS/status bar to correctly display the charging status, and also fixes various bugs:
FS#6891 iPod Nano Charger Support
FS#6940 Nano Car Adapter Mode enabled
FS#10591 iPod nano reboots on idle poweroff when plugged in

DMA is only used for reading because writing seems to be slower with DMA.
Only requests which are cacheline aligned (16 bytes) will use DMA, so many
requests will still use PIO at this point; a later change will align more
reads.
Part of FS#9708, original DMA code by Boris Gjenero (dreamlayers).
