drm: Lower priority of "EDID checksum is invalid" message
The priority goes from "error" to "debug".
Connectors are polled every 10 seconds. Reading EDID is part of this
polling. However, when an invalid EDID is returned, this error message
is logged. When using Newcons for instance, having a kernel message

Plumb the cn_grab and cn_ungrab routines down into the uart

characters. Rather than try to create a cooperative buffering system
for the low level kernel console, instead just mask out the ISR. For
NS8250 and decsendents this isn't needed, since interrupts only happen
after 14 or more characters (depending on the fifo settings). Plumb
such that these are optional so there's no change in behavior for all
the other UART clients. ddb worked on this platform because all
interrupts were disabled while it was running, so this problem wasn't

In r248885 I have reduced size of fake uio resid that ng_ksocket(4) passes
to the soreceive(). This exposed a bug. When reading from a raw socket,
when our fake limit is depleted, we receive a truncated mbuf chain, with
m->m_pkthdr.len > m_length(m). The first problem is that MSG_TRUNC was not
handled. The second one is that we didn't reinit uio_resid in our endless
loop (neither flags), and if socket buffer contained several records, then
we quickly deplete our fake limit. The third bug, actually introduced in
r248885, is that MJUMPAGESIZE isn't enough to handle maximum packet that
ng_ksocket(4) can theoretically receive.
Changes:
- Reinit uio_resid and flags before every call to soreceive().
- Set maximum acceptable size of packet to IP_MAXPACKET. As for now the
module doesn't support INET6.
- Properly handle MSG_TRUNC return from soreceive().

The previous code was checking the "VGA Enable" bit on the video card's
parent PCI-to-PCI bridge only. This didn't work for the case where the
video card is attached to the root PCI bus (ie. the card has no parent
PCI-to-PCI bridge).
Now, the new code:
1. checks the "VGA Enable" bit on the parent bridge only if it's a
PCI-to-PCI bridge;
2. always checks the "I/O" and "Memory address space decoding" bits
on the video card itself.
However, vendor-specific bits are not used.
This fixes the use of many integrated Radeon cards: without this patch,
we fail to detect them as the boot display and, when radeonkms looks for
the Video BIOS, it skips the shadow copy made by the System BIOS. It
then fails to fully initialize the card, because the shadow copy is the
only way to read the Video BIOS in these situations. A workaround was to
force the boot display selection using the "hw.pci.default_vgapci_unit"
tunable.
A previous version of this patch added a new function doing the checks.
Now, the vga_pci_is_boot_display() function is used to perform the
checks (only until the boot display is found) and return if the given
device is the boot display or not.
Furthermore, vga_pci_attach() logs "Boot video device" if the card being
attached it the Chosen One:
vgapci0: <VGA-compatible display> [...]
