I removed the same sort of workaround for OpenBSD within the
configure script with commit 4dcc3f58
but didn't bother to grep further to come across this same chunk
of code in the curses code itself. So the following diff removes
the same workaround chunk within the curses code.

This patch updates the seabios submodule to commit
b1c35f2b28cc0c94ebed8176ff61ac0e0b377798.

Most important change is that seabios sets the busmaster bit
in the pci config space for the lsi and esp scsi host adapters.
Since commit 1c380f94 qemu
is strict here and disallows any dma access when the bit is
clear.

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.
