in inteldrm(4).
The Intel integrated graphics device has a major design flaw where it needs
legacy VGA io access to disable VGA mode completely. This only works if
legacy VGA io routing is setup such that it actually reaches the IGD. This
typically isn't the case if the primary VGA device is a discrete graphics
device. To make sure we don't whack that device we have to temporarily
route legacy VGA io access to the IGD.
Fixes the "black screen" issue reported by Timo Myrra and others.

7Y250M0, refuse to do DMA unless the transfer mode has been set. This causes
reads (and presumably writes) to time out.
Unlike the wdc code, this only sets the UltraDMA transfer mode. If we ever
want to support ancient PATA drivers through the atascsi layer, we probably
need to set the PIO and/or MWDMA transfer modes as well.

positions when deciding how much work to do, and to adjust rl_tx_free with
atomic operations; split the flag that indicates whether we're using
timer based interrupts or not out into a separate field so it can be
changed from interrupt context without needing a lock; take the kernel
lock when calling re_init and re_start from interrupt context; add an
interrupt barrier in re_stop; and finally mark the interrupt handler
as mpsafe.

periodically reseeded. rdseed should give us more bits of entropy.

Use the size info in struct sr_boot_volume, and not the uninitialized
info in the disklabel, when checking the GPT protective MBR. Now
both GPT and MBR formatted softraid volumes actually boot.
As a bonus add prototype for gpt_chk_mbr().
