It turns out the prescaler fields in OST_CTRL are 2 bits wide,
not 3. The programming manual (as usual) is ambiguous and its
diagram shows 2-bit wide fields, but the bit positions in the
text give a 3-bit wide field. Ingenic's Linux code and my own
testing shows that they are, in fact, 2 bits wide.
This caused the OST2 divisor to be 16 instead of 4; the OST1
divisor was correct. This means that all udelay/mdelay calls
took 4x longer than they should've. After this change the OST2
prescaler will be 4, as intended, and udelay/mdelay calls will
wait for the intended duration.

I think this covers everything now, although some fields are missing
enum values. Those can be added in if and when they are needed.

This only required a minor patch to the usb-designware driver due
to DMA requiring physical addresses -- on the X1000, these differ
from virtual addresses so we have to do the usual conversion.
Both the mass storage and HID drivers work, but there are a few
issues so this can't be considered 100% stable yet.
- Mass storage might not be detected properly on insertion,
and USB has to be replugged before it shows up
- HID driver may occasionally panic or hang the machine
