This patch updates the seabios submodule to commit
b1c35f2b28cc0c94ebed8176ff61ac0e0b377798.

Most important change is that seabios sets the busmaster bit

Since commit 1c380f94 qemu
is strict here and disallows any dma access when the bit is

Hotplugging them simply doesn't work, so tag them accordingly to
avoid users trying and then crashing qemu.

For xhci there is nothing fundamental which prevents hotplug from
working, we'll "only" need a exit() function which cleans up
everything properly.  That isn't for 1.3 though.

For ehci+uhci+ohci hotplug can't be supported until qemu gains the
capability to hotplug multifunction pci devices.

The virtio-scsi config space is, by specification, in guest endian (which
is ill-defined, but there you go).  In virtio_scsi_get_config() we set up
all the fields in there, using stl_raw().  Which is a problem for the
max_channel and max_target fields, which are 16-bit, not 32-bit.  For
little-endian targets we get away with it by accident, since the first
two bytes will still be correct, and the extra two bytes written (with
zeroes) will be overwritten correctly by the next store.

But for big-endian guests, this means the max_target field ends up as zero,
which means the guest will only recognize a single disk on the virtio-scsi
bus.  This patch fixes the problem.

The virtio-scsi specification does not specify the correct endianness for
fields in the request structure.  It's therefore best to assume that it is
"guest native" endian since that's the (stupid and poorly defined) norm in
virtio.

However, the qemu device for virtio-scsi has no byteswaps at all, and so
will break if the guest has different endianness from the host.  This patch
fixes it by adding tswap() calls for the sense_len and resid fields in
the request structure.  In theory status_qualifier needs swaps as well,
but that field is never actually touched.  The tag field is a uint64_t, but
since its value is completely arbitrary, it might as well be uint8_t[8]
and so it does not need swapping.
