Add support for polling com devices when no interrupt is available.

branches: 1.18.8;
Use {isa,pci}_intr_establish"_xname"() for intrctl(8).

branches: 1.17.6; 1.17.20;
make pci_intr_string and eisa_intr_string take a buffer and a length
instead of relying in local static storage.

On x86, print the I/O address of lpt_puc as for com_puc so that hacks
using iopl/ioperm can be told where to find the parallel port.

Closes PR kern/43683.

Since puc(4) serial ports are typically not identified in the
BIOS COM[1234] table, the I/O address must be manually set using
installboot(8) in order to enable a serial console.
Print the address here so the user doesn't have to dig through
PCI configuration space to find it.

Enable suspend/resume hooks.

Split the softc from the device_t for all lpt(4) variants and attachments
except the ppbus stuff (which doesn't compile) and ulpt(4) which is
unrelated and can be dealt with separately.

As usual, it comes with related cosmetic changes.

add a driver for "PCI 'universal' communications" cards, that is, PCI cards
which contain 'standard' com- and lpt-type ports. Some of these present
as PCI simple-communications/serial or simple-communications/parallel
devices, but many do not. (Additionally, there is no document that I can
find that describes the "specific well-konwn register-level" description
of how the 'standard' devices' config space headers shold work.) Eventually,
some of the devices driven by this code should become simple pci attachments
for the 'lpt' and 'com' drivers, but that requires solid documentation.
