We should be using resource_size_t and unsigned types correctly, otherwise
we sign extend the flags on a 64bit box, which is not what we want.

The "Pin" and "Copy" configuration registers (CISREG_SCR, CISREG_PPR)
do not seem to be utilized anywhere. If a device would request a
write to these registers, "0" would be written. Continue to do so, but
warn of unexpected behavior -- and remove the "Pin" and "Copy" entries
from config_req_t.

Insert PCMCIA device resources into the resource tree. However, this is
currently only implemented for sockets which do not statically map the
resources.

Introduce a new field into struct pcmcia_device named "resource" and of
type struct resource *, which contains the IO port ranges allocated for
this device. Memory window ranges and registration with the resource
trees will follow at a later date.

Clean up the alloc_io_space() function by moving most of it to
the actual resource_ops. This allows for a bit less re-directions.
Future cleanups will follow, and will make up for the code
duplication currently present between rsrc_iodyn and rsrc_nonstatic
(which are hardly ever built at the same time anyway, therefore no
increase in built size).

Setup the IRQ to be used by PCMCIA drivers already during the device
registration stage, making use of a new function pcmcia_setup_irq().
This will allow us to get rid of quite a lot of indirection in the
future.

After a CIS update -- or the finalization of the resource database --,
proceed with the re-scanning or re-querying of PCMCIA cards only in
a separate thread to avoid deadlocks.

replace pcmcia_socket->lock and pcmcia_dev_list_lock by using the
per-socket "ops_mutex", as we do neither need different locks
nor a spinlock here.

As PCMCIA is the only real user of CIS access functions, include
cistpl.c in the PCMCIA module, not in the PCMCIA & CardBus core
module.

As release_resoure_db() used to be called only from one place, and

Do not lock the socket driver module on card insert, as
the PCMCIA core can handle a socket module removal, at least
if we add a call to socket_remove() on pccardd()'s shutdown.

pcmcia_get_window() and pcmcia_get_mem_page() were only called from
pcmcia_ioctl.c. Therefore, move these functions to that file, and
remove the useless EXPORTs.
