nubus: Rework /proc/bus/nubus/s/ implementation
The /proc/bus/nubus/s/ directory tree for any slot s is missing a lot
of information. The struct file_operations methods have long been left
unimplemented (hence the familiar compile-time warning, "Need to set
some I/O handlers here").
Slot resources have a complex structure which varies depending on board
function. The logic for interpreting these ROM data structures is found
in nubus.c. Let's not duplicate that logic in proc.c.
Create the /proc/bus/nubus/s/ inodes while scanning slot s. During
descent through slot resource subdirectories, call the new
nubus_proc_add_foo() functions to create the procfs inodes.
Also add a new function, nubus_seq_write_rsrc_mem(), to write the
contents of a particular slot resource to a given seq_file. This is
used by the procfs file_operations methods, to finally give userspace
access to slot ROM information, such as the available video modes.
