c4717ac049 aw_nmi: add support for a31/a83t's r_intc
We currently support the a83t's r_intc in a somewhat hack-ish way; our .dts
describes it as nmi_intc, and uses a subset of the actual register space to
make it line up with a20/a31 nmi offsets.

This breaks with the recent 4.14 update describing r_intc using the full
register space, so update aw_nmi to use the correct register offsets with
the right compat data in a way that doesn't break our current dts with
nmi_intc or upstream with r_intc described.

9346e9130d Return the struct intr_pic pointer from intr_pic_register. This will be
needed in later changes where we may not be able to lock the pic list lock
to perform a lookup, e.g. from within interrupt context.

cd642c88a1 INTRNG - redefine struct intr_map_data to avoid headers pollution. Each
struct associated with some type defined in enum intr_map_data_type
must have struct intr_map_data on the top of its own definition now.
When such structs are used, correct type and size must be filled in.

There are three such structs defined in sys/intr.h now. Their
definitions should be moved to corresponding headers by follow-up
commits.

While this change was propagated to all INTRNG like PICs,
pic_map_intr() method implementations were corrected on some places.
For this specific method, it's ensured by a caller that the 'data'
argument passed to this method is never NULL. Also, the return error
values were standardized there.

30c05743c4 Add support for the Non-maskable interrupt driver found in the Allwinner A20 and A31 SoCs.
This is normally used for the PMU.
