This tidies up the mca driver API and places it into its own file.
The main part converts the smc-mca driver to using the sysfs probe interface
(and thus no-longer needs its entry in Space.c). I had to rename the io and
irq parameters to be ultra_io and ultra_irq to prevent clashes.
I think this one concludes all the modifications to drivers of actual MCA
cards I have access to.

# This is a BitKeeper generated patch for the following project:
# Project Name: Linux kernel tree
# This patch format is intended for GNU patch command version 2.5 or higher.
# This patch includes the following deltas:
# ChangeSet 1.847 -> 1.850
# drivers/net/Space.c 1.12 -> 1.13
# drivers/net/smc-mca.c 1.6 -> 1.7
# drivers/mca/mca-bus.c 1.2 -> 1.3
# include/linux/mca.h 1.4 -> 1.5
# drivers/mca/Makefile 1.2 -> 1.3
# (new) -> 1.1 drivers/mca/mca-driver.c
#
# The following is the BitKeeper ChangeSet Log
# --------------------------------------------
# 02/11/22 jejb@mulgrave.(none) 1.848
# add mca-driver handling
#
# Tidies up the handling of MCA drivers
# --------------------------------------------
# 02/11/22 jejb@mulgrave.(none) 1.849
# update smc-mca to new MCA API
#
# This updates to the new API and means that smc-mca is now probed similarly to a PCI device
# --------------------------------------------
# 02/11/22 jejb@mulgrave.(none) 1.850
# add mca-driver.c file
# --------------------------------------------
