v3: Fix up drmP and IRQ flag, thanks Sam
v2: Address review from Noralf and Daniel, add maintainers patch

This driver is for the ASPEED BMC SoC's GFX display hardware. This
driver runs on the ARM based BMC systems, unlike the ast driver which
runs on a host CPU and is is for a PCIe graphics device that happens to
live in the BMC's silicon, but is otherwise available for use by the
BMC.
