puc: Make kernel module working

We need uart_bus_puc.c in the module for it to work.

sys: Remove $FreeBSD$: one-line sh pattern

Remove /^\s*#[#!]?\s*\$FreeBSD\$.*$\n/

pccard: Remove puc(4) PC Card attachment

Remove PUC's pccard attachment. This removes support for 16-bit PC
Cards.

Relnotes: Yes

Add PNP info to the PCI attahement of the puc driver.

Adjust sys/conf/files and sys/modules/puc/Makefile to omit
pucdata.c now tht it's included by puc_pci.c.

Kill MFILES and find things automatically. It turned out to be only
lightly used. Find the proper .m file when we depend on *_if.[ch] in
the srcs line, with seat-belts for false positive matches. This uses
make's path mechanism. A further refinement would be to calculate this
once, and then pass the resulting _MPATH to modules submakes.

Rewrite of puc(4). Significant changes are:
o Properly use rman(9) to manage resources. This eliminates the

Rewrite of puc(4). Significant changes are:
o Properly use rman(9) to manage resources. This eliminates the
need to puc-specific hacks to rman. It also allows devinfo(8)
to be used to find out the specific assignment of resources to
serial/parallel ports.
o Compress the PCI device "database" by optimizing for the common
case and to use a procedural interface to handle the exceptions.
The procedural interface also generalizes the need to setup the
hardware (program chipsets, program clock frequencies).
o Eliminate the need for PUC_FASTINTR. Serdev devices are fast by
default and non-serdev devices are handled by the bus.
o Use the serdev I/F to collect interrupt status and to handle
interrupts across ports in priority order.
o Sync the PCI device configuration to include devices found in
NetBSD and not yet merged to FreeBSD.
o Add support for Quatech 2, 4 and 8 port UARTs.
o Add support for a couple dozen Timedia serial cards as found
in Linux.

Create a puc module. Not connected to the build until I can test it on
more machines.
